<P>PROBLEM TO BE SOLVED: To provide a resin frame which eliminates the torque increase and uneven rotation occurring in the twisting produced by fixing of frames to each other in a cartridge state and provides the reduction of a cost and man-hours for assembly by the curtailment of screws and the simplification of bonding process steps and a method of bonding a process cartridge. <P>SOLUTION: Side covers and a developing device unit are fixed in the state of maintaining the spacing in a longitudinal direction before joining by performing resin joining. Namely, a photoreceptor unit and the developing device unit can be bonded by eliminating the torque increase and uneven rotation occurring in the twisting and the distortion of the side covers. Since the curtailment of the screws and the bonding process steps is simple, the method is effective in the reduction of the cost and the man-hours for assembly. <P>COPYRIGHT: (C)2003,JPO |
