GROUNDING DEVICE FOR PHOTORECEPTOR DRUM, AND PHOTORECEPTOR DRUM UNIT FOR IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a grounding device for a photoreceptor drum attaining excellent image formation while preventing the occurrence of noise at a conductive part of a drum shaft and a grounding member without degrading the strength of the drum shaft.;SOLUTION: The grounding device electrically connects the conductive drum shaft 15 to the photoreceptor drum 12 mounted to the drum shaft 15 rotatably through an insulating flange 13, by the grounding member 19. The grounding member 19 is formed of a conductive resin, and the grounding member 19 is formed with a grounding plate 19a provided with a contact piece 19b contacting the photoreceptor drum 12, and an elastic contact piece 19c contacting the drum shaft 15 to electrically connect the drum shaft 15 to the photoreceptor drum 12.;COPYRIGHT: (C)2009,JPO&INPIT
