ELECTRIFYING DEVICE, IMAGE FORMING DEVICE AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide an electrifying device capable of realizing the reduction of cost by making parts common. SOLUTION: This electrifying device is constituted so that both ends of core bars 2a and 2a' provided at the center parts of electrifying rollers (electrifying member) 2 and 2' pressured and brought into contact with an electrophotographic sensitive body are rotatably supported by a bearing member 1, and the member 1 is energized by a spring (elastic member) 4 toward the photosensitive body so as to press the rollers 2 and 2' to the photosensitive body. In the device, semicircular recessed parts 1A and 1B for bearing the core bars 2a and 2a' are formed at least at two spots of the member 1. Since the plural semiconductor recessed parts 1A and 1B for bearing the core bars 2a and 2a' of the rollers 2 and 2' are formed on the same member 1, the plural rollers 2 and 2' having the core bars 2a and 2a' whose diameters are different are supported by the same member 1. Thus, the parts are made common so as to realize the reduction of cost of the device.
