Abstract:
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, comprising: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;position signal generation means for outputting a position signal representing a scanning position in a scan line of a first color 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; andcontrol means for controlling rotation driving of said rotation polygon mirror corresponding to second and subsequent colors, in response to the position signal of the first color, such that the image formation positions of the second and subsequent colors on the photosensitive body coincide with the image formation position of the first color.
