ABSTRACT:
An image forming apparatus includes an image carrier that a plurality of toner images of differing colors are formed on a surface, and an intermediate transfer belt positioned opposite the image carrier, the toner images formed on the image carrier being primarily transferred onto an intermediate transfer belt in a superimposed condition, and being collectively secondarily transferred from the intermediate transfer belt onto a transfer material, and the toner images of the two colors set to be approximately identical in screen angle being consecutively transferred in a superimposed condition onto the intermediate transfer belt. A drive load fluctuation correction unit corrects the drive load to the intermediate transfer belt in accordance with a cleaning device moving into and out of engagement with the intermediate transfer belt.
