Abstract
In forming a multi-colored image by superimposing a plurality of plane images, positional offsets of the plane images are prevented, thereby obtaining high quality color images. The timing at which image data corresponding to each plane image is generated is controlled in accordance with the phase difference between the sub-scanning start signal indicating the rotational timing of an image carrier and the main-scanning start signal representing the rotational timing of a rotating polygonal mirror. Various controls are further performed.
