PROBLEM TO BE SOLVED: To precisely fix positional relation between a latent image device and a photoreceptor and to firmly join them by integrally fitting a holding member to which the latent image device is fitted and the photoreceptor by using a side plate. SOLUTION: One end side 21 of the latent image device 2 is fitted to a main body housing 1 through a positioning pin P and the other end side 22 thereof is fitted to the housing 1 and the integrated side plate 4 through the pin P. The shaft 3a of the photoreceptor 3 is fitted to the housing 1 and the plate 4 through a bearing B so that the photoreceptor 3 can be rotated. Since the latent image device 2 and the photoreceptor 3 are integrally fixed by the housing 1 and the plate 4, the positional relation between them is precisely fixed and an electrostatic latent image can be written at a precise position on the photoreceptor 3 from the latent image device 2. Besides, the plate 4 is fitted so as to be freely attached and detached. |
