Abstract
When a monochromatic copy mode is to be executed, a control section sets a read mode in a scanner section so as to enable the scanner section to read an image at high speed by means of only a line sensor K, sets in an image processing section an image process that can print monochromatic image information, which is sent from the scanner section, with a single black color in the printer section, and sets in the printer section a monochromatic print mode that can print a black image at high speed, thereby controlling a monochromatic copy operation.
Claims15
An image forming apparatus comprising:
- a first image reader which reads an image at a first scan speed via a filter, which passes light of a specific wavelength band, and convert the image to image information;
- a second image reader which reads an image at a second scan speed, which is higher than the first scan speed, and convert the image to luminance image information that is luminance information;
- a first printer which prints an image on the basis of the image information that is read by the first image reader on a paper;
- and
- a second printer which prints an image on the basis of the luminance image information that is read by the second reader on a paper at a speed that is higher than a speed of the first printer.
An image forming method comprising:
- reading by a first image reader an image at a first scan speed via a filter, which passes light of a specific wavelength band, and converting the image to image information that is luminance information;
- reading by a second image reader an image at a second scan speed, which is higher than the first scan speed, and converting the image to image information;
- printing by a first printer an image on the basis of the image information that is read by the first image reader on a paper;
- and
- printing by a second printer an image at a speed that is higher than a speed of the first printer, on the basis of the image information that is read by the second reader on a paper.
