Abstract
PURPOSE: To reduce the weight of drum and miniaturize the drive source, by using a photosensitive drum having a photoreceptor layer formed on the outer circumference of a cylindrical substrate made of nonmetallic material.
CONSTITUTION: A photosensitive drum 1 is constituted with a cylindrical substrate 2 made of nonmetallic material such as synthetic resin, and a photoreceptor layer 3 coated with ZnO or the like on the outer circumference. This drum 1 is provided in the main body of a copying machine 4, and is supported by a cylindrical supporting member 5 which rotates in the direction of arrow in cooperation with the drive source. Charger 6, exposure device 7, developing device 8, transfer device 9, cleaning device 10, and destaticizing lamp 11 are provided sequentially in the rotating direction on the outer circumference of the drum 1. Thus, the weight of the photosensitive drum is reduced, and the manufacturing cost may be greatly reduced.
