Abstract

An image forming apparatus capable of preventing degradation of image quality and reducing time required for rotational phase control. Toner images different in color are formed on a plurality of photosensitive drums, respectively. The toner images are transferred onto an intermediate transfer belt in superimposed relation. A motor controller performs phase control for bringing phases of the respective photosensitive drums into predetermined relation based on a rotational phase difference detected using phase detection sensors. When the rotational phase difference is out of a predetermined range, the motor controller performs the phase control with the photosensitive drums and the intermediate transfer belt separated from each other, whereas when the rotational phase difference is within the predetermined range, the motor controller performs the phase control with the photosensitive drums and the intermediate transfer belt in contact with each other.
