Abstract

Official abstract text for this publication.

An image forming apparatus which allows a user to freely select a desired image quality is provided. The control unit 60 sets a of registration set value A 1 for determining a color registration error suppression level and a dropout set value A 2 for determining a dropout occurrence suppression level. Also, the control unit 60 sets a differential circumferential speed which is the difference between the circumferential speed of photoreceptor drums 1 Y to 1 K and the circumferential speed of an intermediate transfer belt 6 on the basis of the color registration set value A 1 and the dropout set value A 2 . Then, the control unit 60 controls the belt drive motor 61 and the drum drive motor 62 on the basis of the differential circumferential speed which is set.

First claim

Opening claim text (preview).

The invention claimed is: 1. An image forming apparatus comprising: a plurality of image bearing members configured to bear images of predetermined color components respectively; an intermediate transfer belt configured to form a superimposed image by successively transferring the images from said plurality of image bearing members on said intermediate transfer belt; a first drive unit configured to rotate said plurality of image bearing members; a second drive unit configur…
