ABSTRACT:
An electrical grounding member for an electrophotographic photosensitive drum, includes a base plate; a hole formed in a substrate, for receiving a conduction shaft for supporting the electrophotographic photosensitive drum; a first contact portion provided in the base plate and elastically contactable to the conduction shaft; a second contact portion, provided in the base plate, for elastically contacting an inner surface of a cylinder of the electrophotographic photosensitive drum; a third contact portion, provided in the base plate, for elastically contacting an inner surface of a cylinder of the electrophotographic photosensitive drum. The second contact portion and third contact portion are disposed at symmetrical positions relative to each other with respect to a center line of a contact portion between the first contact portion and the conduction shaft.
