Abstract
Based on whether image formation is to be performed on an one side or both sides of record paper, and on whether image data concerning image formation is image data of an one-sided document or image data of a double-sided document, it is judged whether a blank page or a blank sheet whose both sides are blank pages is included, and image formation is performed excluding said blank page or both sides of the blank sheet based on said judgment result.

An image forming apparatus which performs image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, comprising,
- a controller capable of judging whether a blank page in which no object is recorded is included, based on said image data,
- wherein said controller is further capable of judging whether said image data is the image data of the one-sided document or the image data of the double-sided document in a case where image formation is to be performed on both sides of a record sheet, and
- wherein when said controller judges that the image data is the image data of the one-sided document, said controller judges whether a blank page is included, and when said controller judges that the blank page is included, said image formation is performed excluding said blank page.
An image forming apparatus which performs image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, comprising:
- a blank page judging section for judging whether a blank page in which no object is recorded is included, based on said image data, and
- a document judging section for judging whether said image data is the image data of the one-sided document or the image data of the double-sided document in a case where image formation is to be performed on both sides of a record sheet,
- wherein when said document judging section judges that the image data is the image data of the one-sided document, said blank page judging section judges whether the blank page is included, and when said blank page judging section judges that the blank page is included, said image formation is performed excluding said blank page.
An image forming method for performing image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, comprising:
- a blank page judging step of judging whether a blank page in which no object is recorded is included, based on said image data;
- and
- a document judging step of judging whether said image data is the image data of the one-sided document or the image data of the double-sided document in a case where image formation is to be performed on both sides of a record sheet;
- and
- a step of, when judgment is made as to whether the blank page is included at the blank page judging step when it is judged that the image data is the image data of the one-sided document at the document judging step and it is judged that the blank page is included, performing said image formation excluding said blank page.
An image forming method for performing image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, comprising:
- a judging step of judging whether image formation is to be performed on a one side of a record sheet or on both sides of a record sheet;
- a document judging step of judging whether said image data is image data of a one-sided document or image data of a double-sided document when it is judged that image formation is to be performed on both sides of a record sheet at said judging step;
- a blank page judging step of judging whether a blank page in which no object is recorded is included, based on said image data, when it is judged that image formation is to be performed on a one side of a record sheet at said judging step, or when it is judged that said image data is image data of an one-sided document at said document judging step;
- a blank sheet judging step of judging whether a blank sheet whose both sides are blank pages is included based on said image data, when it is judged that image formation is to be performed on both sides of a record sheet at said judging step and it is judged that said image data is image data of a double-sided document at said document judging step;
- a step of, when it is judged that a blank page is included at said blank page judging step, performing image formation excluding said blank page;
- and
- a step of, when it is judged that a blank sheet is included at said blank sheet judging step, performing image formation excluding said both sides of the blank sheet.
A computer-readable recording medium storing a computer program for causing a computer to perform image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, said computer program comprising:
- a blank page judging step of causing a computer to judge whether a blank page in which no object is recorded is included, based on said image data;
- a document judging step of causing a computer to judge whether said image data is the image data of the one-sided document or the image data of the double-sided document in a case where image formation is to be performed on both sides of a record sheet;
- and
- a step of, when judgment is made as to whether the blank page is included at the blank page judging step in the case where the image data is the image data of the one-sided document at the document judging step and it is judged that the blank page is included, causing a computer to perform said image formation excluding said blank page.
A computer-readable recording medium storing a computer program for causing a computer to perform image formation on a one side or both sides of a record sheet, based on image data of a one-sided document constituted of a sheet which has an object such as a character and a figure recorded on a one side thereof, or image data of a double-sided document constituted of a sheet which has objects recorded on both sides thereof, said computer program comprising:
- a judging step of causing a computer to judge whether image formation is to be performed on a one side of a record sheet or on both sides of a record sheet;
- a document judging step of causing a computer to judge whether said image data is image data of a one-sided document or image data of a double-sided document when it is judged that image formation is to be performed on both sides of a record sheet at said judging step;
- a blank page judging step of, causing a computer to judge whether a blank page in which no object is recorded is included, based on said image data, when it is judged that image formation is to be performed on a one side of a record sheet at said judging step, or when it is judged that said image data is image data of a one-sided document at said document judging step;
- a blank sheet judging step of causing a computer to judge whether a blank sheet whose both sides are blank pages is included based on said image data, when it is judged that image formation is to be performed on both sides of a record sheet at said judging step and it is judged that said image data is image data of a double-sided document at said document judging step;
- a step of, when it is judged that a blank page is included at said blank page judging step, causing a computer to perform image formation excluding said blank page;
- and
- a step of, when it is judged that a blank sheet is included at said blank sheet judging step, causing a computer to perform image formation excluding said both sides of the blank sheet.
