ABSTRACT:
An image forming apparatus has a photosensitive drum on which toner images of different colors are formed and sequentially transferred in layers to an intermediate transfer drum. In the continuous color image formation, depending on whether to be the first page or after second page, for example, the control of the correcting system for color mis-registration is switched so that the mechanical effect on the apparatus caused by biasing and unbiasing actions of a transfer roller and an ICL roller toward the intermediate transfer drum in each condition can be suppressed to the minimum without penalties in throughput.
