ABSTRACT:
In a multicolor printing apparatus in which a laser beam is scanned by a rotary polygon mirror to form an electrostatic latent image on a photosensitive medium, multicolor printing is effected by forming images of individual plural colors. When plane mirrors of the rotary polygon mirror which are used for scanning to form the head lines of images of different colors differ from each other, the difference in plane inclination between plane mirrors causes color shift or misregistration and image deformation. In order to prevent this disadvantage, the same mirror plane of the rotary polygon mirror is managed to be used for scanning to form the head lines of images of different colors.
