ABSTRACT:
A recycling method for a process cartridge and a process cartridge produced thereby are provided. The method includes the steps of dismounting a coupling member that couples a first unit and a second unit of the process cartridge so as to separate the first unit and the second unit; machining a connecting portion between a developing device frame of the second unit and a developer frame of the second unit so as to separate the developing device frame and the developer frame from each other without damage to dowels of the developer frame, the dowels are provided in a recessed portion for fitting into holes formed in a seal mounting plate of the process cartridge to thereby position and mount the seal mounting plate; mounting a seal that seals a developer supply opening provided in a developer accommodation portion to supply, to a developing roller of the process cartridge, developer accommodated in the developer accommodation portion; refilling a developer into the developer accommodation portion before or after the mounting step; and recoupling the first unit and the second unit using a coupling member.
