Abstract
It is provided an image formation apparatus which forms a color image by superimposing an image corresponding to each of plural-color image data on an image support body, comprises a light beam generation means for generating a light beam which has been modulated according to each-color image data included in the plural-color image data, a rotation polygon mirror for performing scanning on a photosensitive body by using the light beam, a position signal generation means for outputting a position signal representing a scanning position on the photosensitive body, in case of performing the scanning on the photosensitive body by using the light beam corresponding to first-color image data included in the plural-color image data, and a control means for controlling rotation driving of the rotation polygon mirror corresponding to second and subsequent colors, in response to the position signal. Therefore, it can be obtained a new method for superimposing plural-color plane images without aberration in position, in case of forming a color image by superimposing the plural-color plane images on the image support body such as the photosensitive body, an intermediate transfer body, a record…
