PURPOSE: To keep the image-formation surface of a photoreceptor drum at an almost fixed distance from an image source and to restrain an error in lateral magnification caused by the run-out of the drum to the minimum by pressing the image-formation surface to a rotatable guiding member. CONSTITUTION: This controller is a device for attaching the photoreceptor drum 22 so that the distortion of the image caused by the run-out of the drum 22 is restrained to the minimum by keeping the image-formation surface 23 at the almost fixed distance from the image source. The drum 22 is attached to a rotatable supporting body 70 and elastically pressed to the guiding member 76 by a spring 72. |
