GROUNDING MEMBER, CYLINDRICAL MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve conductibility between a grounding member and a cylindrical member such as an electrophotographic photoreceptor by providing the grounding member with at least two of more 2nd leaf springs abutting on the inner wall of the cylindrical member and setting the positional relation of the 2nd leaf springs to a linear symmetry with the center line of the contact part with the conducting shaft of a 1st leaf spring as the center. SOLUTION: A drum grounding plate 70 is provided with a shaft contact spring 75 functioning as the 1st leaf spring so as to conduct with the conducting shaft, and grounded with the photoreceptor by the 2nd ground spring contact parts 73a and 73b of cylinder springs 77a and 77b functioning as the 2nd leaf spring. The spring 75 is provided with the 1st grounding spring contact part 75a at its end, and the springs 77a and 77b are provided with the 2nd grounding spring contact parts 73a and 73b at their ends. The shape of the 1st and the 2nd grounding spring contact parts 75a and 73a and 73b is triangular. Then, the springs 77a and 77b are constituted as a pair at the position they are linearly symmetric at a nearly perpendicular position with the center line 75c of the spring 75 as the center.
