PURPOSE:To support an image carrier stably and to prevent clogging with toner by arranging an opening part on the side of a cleaning device which is open to a toner storage part at the bearing part of an image carrier, and making the bearing of a prescribed material. CONSTITUTION:Toner is discharged from the cleaning device by a conveyor screw 12 and guided to the toner storage part in a hollow photosensitive body 10 by a pipe 13. A bearing BE for supporting the photosensitive body 10 pivotally on a cartridge C consists of a bearing 19 made of a metallic material such as oil-containing copper sintered alloy and a bearing material 18 made of resin such as PE with good toner separating performance. The photosensitive body 10 is supported tightly on the cartridge C by the bearing BE and the clogging with toner is precluded. |
