Abstract
An image forming apparatus including a drum, an optical scanning mechanism, a development mechanism, an intermediate transfer member, movement detecting mechanisms, and a controller. The intermediate transfer member is rotated in synchronism with a rotation of the drum and receives color toner image multiple times to form thereon a composite color toner image including multiple images of different color toners overlaying one to another. The movement detecting mechanisms detect respective movements of the drum and the intermediate transfer member. The controller controls respective rotations of the drum and the intermediate transfer member with results of respective detection performed by the movement detecting mechanisms.
