ELECTROPHOTOGRAPHIC PHOTORECEPTOR DRUM, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve the grounding stability of an electrophotographic photoreceptor drum. SOLUTION: In the configuration of performing grounding of the photoreceptor drum by electrical connection of a driving shaft (a first electric conduction component) 70 on an image forming apparatus body 100 side and a drum grounding plate (a second electrical conduction component) 71 within the electrophotographic photoreceptor drum 1, the drum-grounding plate 71 has a plane contact section 71a and an arm-like contact section 71b as a contact means and the planar contact section 71a abuts on a driving shaft tip end apex 70a cooperatively with the movement of a driving transmission member 73 and the electrophotographic photoreceptor drum 1, in a direction where both approach each other by the fitting of a threaded hole 73a disposed at the driving transmission member 73 on the image forming apparatus body 100 side and a twisted projection 72a, disposed at one end of the electrophotographic photoreceptor drum 1 and by the pull-in force caused by rotation of the driving transmission member 73, and the arm-like contact section 71b slides on the driving shaft distal end apex 70a.
