Abstract
In accordance with an embodiment, an image forming apparatus comprises a reading section, an image processing section and a printing section. The reading section reads an image on a sheet to generate image data. The image processing section detects, from the image data, an identification image indicating that printing is carried out with decolorable toner, and decolors the detected identification image from the image data. The printing section prints the image data output from the image processing section.
Claims13
An image forming apparatus, comprising:
- a reading section configured to read a first image formed on a first sheet to generate first image data of the first image printed on the first sheet;
- memory that stores pre-set identification image data;
- an input device configured to input information to set a condition of image forming on a second sheet which is different from the first sheet;
- an image processing section configured to:
- determine whether or not the first image data includes an identification image data that matches the pre-set identification image data to detect, from the first image data, the existence of the identification image data;
- identify a first position and a first orientation of an identification image in the first image if the image processing section determined that the first image data includes the identification image data, wherein the identification image is to be created with the identification image data;
- delete the identification image data from the first image data to generate a second image data if the image processing sectioned determined that the first image data includes the identification image data;
- and
- synthesize the pre-set identification image data stored in the memory with the second image data, wherein a second image has a pre-set identification image at a second position and with a second orientation in the second image if the input information indicates that the decolorable toner is to be used for image forming on the second sheet,
- wherein the second image is to be created with the second image data synthesized with the pre-set identification image data,
- wherein the pre-set identification image is to be created with the pre-set identification image data,
- wherein the second position is a position of the pre-set identification image in the second image and same position as the first position of the identification image in the first image, and
- wherein the second orientation is an orientation of the pre-set identification image in the second image and same orientation as the first orientation of the identification image in the first image;
- and
- an image forming section configured to form the second image on the second sheet.

An image forming method, including:
- reading, by a reading section, a first image formed on a first sheet to generate first image data of the first image printed on the first sheet;
- storing, by a set information storage section, pre-set identification image data;
- inputting, by an input device, an information to set a condition of image forming on a second sheet which is different from the first sheet;
- determining, by an image processing section, whether or not the first image data includes an identification image data that matches the pre-set identification image data to detect, from the first image data, the existence of the identification image data;
- identifying, by the image processing section, a first position and a first orientation of an identification image in the first image if the image processing section determined that the first image data includes the identification image data, wherein the identification image is to be created with the identification image data;
- deleting, by the image processing section, the identification image data from the first image data to generate a second image data if the image processing section determined that the first image data includes the identification data;
- synthesizing, by the image processing section, the pre-set identification image data stored in the memory with the second image data,
- wherein a second image has a pre-set identification image at a second position and with a second orientation in the second image if the information indicates that the decolorable toner is to be used for copying the first sheet,
- wherein the second image is to be created with the second image data synthesized with the pre-set identification image data,
- wherein the pre-set identification image is to be created with the pre-set identification image data, wherein the second position is a position of the pre-set identification image in the second image and same position as the first position of the identification image in the first image, and
- wherein the second orientation is an orientation of the pre-set identification image in the second image and same orientation as the first orientation of the identification image in the first image;
- and
- forming, by an image forming section, the second image on the second sheet.
