Abstract

Abstract PURPOSE:To prevent a cleaning member from exerting nonuniform dynamic load to the surface of an image carrier and to prevent further the uneven supply of a developer by using vibration-proof material to a driving system. CONSTITUTION:A magnet roller gear 14, a screw roller gear 15, a drum driving gear 16, a developing gear 17 and a drum rotating gear 18 of a gear system for driving a drum are constituted of vibration-proof materials by which the vibration generated in the stage of rotating the gears 14-18 is prevented. A main motor gear 19 and a chain 20 for transmitting drive of a transmission system for driving a chain wheel 17' for driving development and a chain wheel 16' for driving the drum are formed of vibration-proof materials, by which the propagation of the vibration resulted from the uneven pitch by the chain 20 and the revolution of the main motor to the wheels 16', 17' is prevented.
