Image forming unit and image forming apparatus provided with same

摘要

An image forming unit includes: a photoconductive drum; a charging member extending in a direction along a rotary shaft of the photoconductive drum; and a holding member holding the charging member at a frame member. While held at the frame member with the holding member in between, the charging member is arranged in parallel to the photoconductive drum in contact with a circumferential surface of the photoconductive drum with their rotary shafts in parallel. The holding member and the frame member respectively have interference-preventing-shaped parts provided at a tip part of the holding member in a direction where the holding member is attached and at a position of the frame member receiving the holding member. The interference-preventing-shaped parts are capable of first making contact with each other upon attachment of the charging member to the frame member to thereby prevent interference between the holding member and the photoconductive drum.
