PROBLEM TO BE SOLVED: To accurately position a photoreceptor and a latent image device by forming a supporting member for supporting the shaft of the photoreceptor and an arranging member for attaching the latent image device into one body. SOLUTION: The device is provided with the latent image device 2 for writing an electrostatic latent image on the photoreceptor 1 by emitting light based on image data, and the supporting member 3a for supporting the shaft 1a of the photoreceptor 1 and the arranging member 3b for attaching the latent image device 2 are formed into one body as a frame 3. The frame 3 for supporting both of the photoreceptor 1 and the latent image device 2 is attached to a main body housing A through a holding member 4. The holding member 4 is positioned to the main body housing A through a positioning pin P1, and the installation position of each photoreceptor 1 and the latent image device 2 is decided by the holding member 4 through the frame 3. Thus, a common difference of a distance between the latent image device 2 and the photoreceptor is as long as the distance between the supporting member 3a and the shaft 1a, then, accurate positioning is accomplished. |
