Abstract

PURPOSE:To prevent the stain of an image caused by the damage in a contact part and to prolong the life of a drum by making the hardness of the intermediate layer of a photosensitive body larger than that of a supporting body and directly bringing the position adjusting member of a toner supplying body, etc., into contact with the exposed part of the intermediate layer. CONSTITUTION:The intermediate layer 17 on the cylindrical metal supporting body of the photosensitive body drum 1 is mainly formed of a curing resin including a pigment and its hardness is set larger than that of the metal supporting body. A roller 15 as the position adjusting member provided on the toner supplying body, a cleaning member and an electrifier member, etc., is brought directly into contact with the exposed part of the intermediate layer 17. As a result, the unevenness and the stain of the image caused by a scratch, a scrape and a recess, etc. on a part on which the position adjusting member abuts can be prevented from occurring and since the hardness of the intermediate layer 17 is high, the photosensitive body is not damaged and the life of the drum can be remarkably prolonged.
