成装置。[Claims for Utility Model Registration] 1. An image in which an exposure means for image formation is arranged on the inner circumferential side of a photosensitive drum, which is formed by laminating a transparent conductive layer and a photoconductor layer on a transparent support. In the forming apparatus, a cylindrical spacer formed to have the same diameter or a slightly smaller diameter than the inner peripheral surface of the photoreceptor drum is fixed to the exposure means, and these can be integrally inserted into and removed from the photoreceptor drum. An image forming apparatus characterized in that: 2. The image forming apparatus according to claim 1, wherein a rubbing means is formed on a side of the spacer facing the inner circumferential surface of the drum, and the inner circumferential surface of the drum can be cleaned by the rubbing means. 3. The image forming apparatus according to claim 1, wherein a surface of the spacer that contacts the inner peripheral surface of the drum is formed of a low-friction material. 4. An image forming apparatus in which an exposure means for image formation is disposed on the inner peripheral side of a photoreceptor drum formed by laminating a light-transparent conductive layer and a photoconductor layer on a light-transparent support, wherein the photoreceptor drum A cylindrical spacer formed to have a diameter slightly smaller than the inner peripheral surface of the drum is integrally fixed to the exposure means, and the spacer is moved along a line connecting the axis of the photoconductor drum and the exposure position while being regulated in position. An image forming apparatus characterized in that it is configured to enable
