A remanufacturing method for a process cartridge including a development unit main frame (27), the method comprising: a first gear group dismounting step of dismounting a first gear group (84,85) from a first bearing member (76) mounted to one longitudinal end of the frame, wherein the first gear group includes a driving receiving gear (84) for receiving a driving force from the main assembly of an image forming apparatus when mounted; a supporting member dismounting step of dismounting a supporting member (83) from the first bearing member, the supporting member being provided between the first gear group and a second gear group (86,87,88) for transmitting the driving force to a toner supply roller (25b); a second gear group dismounting step of dismounting the second gear group from the first bearing member, steps of dismounting the first bearing member, development roller (25a) and developing blade (23) from the frame; a refilling step of filling a developer into a developer accommodating portion through a developer supply opening exposed by the developing blade dismounting step; steps of mounting the developing blade to the frame, and the developing roller by engaging its longitudinal ends in holes in the first and second bearing members (76,75); a second gear group mounting step of mounting the second gear group to the first bearing member; a supporting member mounting step of mounting the supporting member to the first bearing member and outside of the second gear group so as to overlap at least a part thereof; a first gear group mounting step of mounting the first gear group to the first bearing member to which the supporting member is mounted. The above described processes, and the structural arrangement having the supporting member (83), prevents the second group of gears from accidentally falling off when disassembling or assembling the process cartridge, simplifying its remanufacturing. <IMAGE> |
