Abstract
A color image forming apparatus of the present invention comprises an intermediate transfer member having a movable surface, a plural image forming units for forming superposed toner images on the intermediate transfer member at a predetermined image forming pitch, and a transfer member for transferring the superposed toner images formed on the intermediate transfer member onto a sheet of paper, wherein the peripheral length of the intermediate transfer member is a non-integral multiple of the image forming pitch.
Claims20
A color image forming apparatus comprising:
- an intermediate transfer belt having a movable surface;
- a first image forming unit for forming a first toner image of a first color on the intermediate transfer belt at a predetermined image forming pitch;
- a second image forming unit for forming a second toner image of a second color to superimpose on the first toner image formed on the intermediate transfer belt at the predetermined image forming pitch, the second image forming unit being disposed downstream of the first image forming unit with respect to the surface-moving direction of the intermediate transfer belt;
- a third image forming unit for forming a third toner image of a third color to superimpose on the first and the second toner images formed on the intermediate transfer belt at the predetermined image forming pitch, the third image forming unit being disposed downstream of the second image forming unit with respect to the surface-moving direction of the intermediate transfer belt;
- a fourth image forming unit for forming a fourth toner image of a fourth color to superimpose on the first, the second and the third toner images formed on the intermediate transfer belt at the predetermined image forming pitch, the fourth image forming unit being disposed downstream of the third image forming unit with respect to the surface-moving direction of the intermediate transfer belt;
- and
- a transfer roller for transferring the superimposed toner images formed on the intermediate transfer belt onto a sheet of paper;
- wherein the peripheral length of the intermediate transfer belt is a non-integral multiple of the image forming pitch.
The color image forming apparatus of claim 41, wherein the paper length is a maximum paper length of usable papers.
