PROBLEM TO BE SOLVED: To surely prevent the positional deviation of the end of a magnet roller and an end sealing member in an axial direction without making the device larger by energizing the magnet roller in the axial direction by a feed member. SOLUTION: A feed plate 10k being the feed member is attached to a side plate and a part of the feed plate 10k2 comes in contact with a feed contact 10i. A leaf spring part 10k1 is provided on the feed plate 10k as a contact member, and comes in contact with the end 10b3 of the magnet roller 10b so as to energize it in the axial direction. Therefore, the positioning accuracy of the magnet roller 10b and the developing end sealing member is improved without depending on the accuracy of parts. Thus, toner leakage is prevented and the developing end sealing member is narrowed, so that the torque of a developing sleeve does not become high and the process cartridge is miniaturized. Since an energizing member is constituted as a part of the feed plate 10k, the number of parts is not increased and cost is reduced. |
