An electrical contact member is usable with a process cartridge, and is for establishing an electrical connection between the process cartridge and a main assembly of an electrophotographic image forming apparatus, when the process cartridge is mounted to the main assembly of the apparatus. The process cartridge includes an electrophotographic photosensitive drum and a process device actable on the photosensitive drum. The electrical contact member includes: a base member; a mounting portion for mounting the base member to a frame of the process cartridge; a positioning portion for positioning the base member in the frame when the base member is mounted to the frame of the process cartridge by the mounting portion; and an electrical contact portion, projected from the base member, for establishing an electrical connection with a main assembly side electrical contact member, which is provided in the main assembly of the apparatus, by pressing in a direction against the main assembly side electrical contact member when the process cartridge is mounted to the main assembly of apparatus. This direction is different from a mounting direction in which the process cartridge is mounted to …
