Abstract
An image forming apparatus includes: an image forming unit configured to form an image on a sheet based on image forming condition; a reader configured to convey the sheet, and read a test image on the sheet while the sheet is conveyed; and a controller configured to: control the image forming unit to form the image and the test image on a same sheet; control the reader to read the test image on the same sheet; and generate the image forming condition for adjusting an density of an image to be formed by the image forming unit, based on a reading result of the test image by the reader.
Claims7
An image forming apparatus, comprising:
- an image forming unit configured to form an image on a sheet based on image forming condition;
- a reader configured to convey the sheet, and read a test image on the sheet while the sheet is conveyed;
- and
- a controller configured to:
- control the image forming unit to form the image and the test image on a same sheet;
- control the reader to read the test image on the same sheet;
- and
- generate the image forming condition for adjusting an density of an image to be formed by the image forming unit, based on a reading result of the test image by the reader,
- wherein, in a case where the test image is formed at a print job in which the image forming unit forms images on both surfaces of a sheet, the controller controls the image forming unit to form the test image on a first surface of the sheet without forming the test image on a second surface of the sheet opposite to the first surface of the sheet,
- wherein, in a case where the second image on the second surface overlaps back side of a test image area in which the test image is formed, the second image on the second surface has a blank area that corresponds to back side of the test image area of the first surface, and
- wherein the blank area has no image.
An image forming apparatus comprising:
- an image forming unit configured to form an image on a sheet based on image forming condition;
- a reader configured to convey the sheet, and read a test image on the sheet while the sheet is conveyed;
- and
- a controller configured to:
- control the image forming unit to form the image and the test image on a same sheet;
- control the reader to read the test image on the same sheet;
- and
- generate the image forming condition for adjusting an density of an image to be formed by the image forming unit, based on a reading result of the test image by the reader,
- wherein, in a case where the test image is formed at a print job in which the image forming unit forms images on both surfaces of a sheet, the controller controls the image forming unit to form the test image on a first surface of the sheet without forming the test image on a second surface of the sheet opposite to the first surface of the sheet,
- wherein, in a case where the second image on the second surface overlaps back side of a test image area in which the test image is formed, the second image on the second surface has an uniform density area that corresponds to back side of the test image area of the first surface, and
- wherein the uniform density area has an image with uniform image density.
