<P>PROBLEM TO BE SOLVED: To further increase positional accuracy of an electrode member with respect to a bearing frame body, and to prevent falling of the electrode member and floating over the bearing frame body during physical distribution. <P>SOLUTION: A cartridge comprises a contact part 19 formed by injection molding of a conductive resin to a bearing member 20 and to be a conductive path between an apparatus body and a developing roller when the cartridge is attached to the apparatus body, the contact part having: a penetration part 19f penetrating through a through-hole 20c; a core metal support part 19b arranged at one end side in an axial direction of the penetration part 19f and rotatably supporting the developing roller; and a contact face 19a arranged at other end side in the axial direction of the penetration part 19f and extending toward a direction crossing the axial direction, the contact part being arranged to sandwich the bearing member 20 between the core metal support part 19b and the contact face 19a in the axial direction, in which at least one of the core metal support part 19b and the contact face 19a has taper portions (20h and 20i) which are inclined with respect to a face orthogonal to the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
