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:
- first image reading means for reading 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;
- second image reading means for reading an image at a second scan speed, which is higher than the first scan speed, and converting the image to image information;
- first output image forming means for forming an output image on the basis of the image information that is read by the first image reading means;
- and
- second output image forming means for forming an output image on the basis of the image information that is read by the second image reading means.
An image forming apparatus having a first copy mode wherein a to-be-copied original is copied with a plurality of colors corresponding to colors of the to-be-copied original, and a second copy mode in which the to-be-copied original is copied with a single color, and
- when copy is executed in the first copy mode, the to-be-copied original is read by a plurality of first light receiving element arrays with optical filters that pass lights of different wavelength bands, and when copy is executed in the second copy mode, the to-be-copied original is read by a second light receiving element array without an optical filter.
An image forming apparatus having a scan mode wherein a to-be-copied original is copied with a plurality of colors corresponding to colors of the to-be-copied original, and a single-color copy mode in which the to-be-copied original is copied with a single color, and
- when the to-be-copied original is read in the scan mode, the to-be-copied original is read by a plurality of first light receiving element arrays with optical filters that pass lights of different wavelength bands, and when the to-be-copied original is copied in the single-color copy mode, the to-be-copied original is read by a second light receiving element array without an optical filter.
