Abstract
A remanufacturing method of remanufacturing a process cartridge includes (a) a step of preparing a used process cartridge which includes a toner developing container, a cleaning container and pins for coupling the toner developing container and the cleaning container at opposite longitudinal ends of the process cartridge, the toner developing container including a toner accommodating portion, a toner supply opening, a developing roller and a developing blade. The cleaning container includes an electrophotographic photosensitive drum. The method also includes a container separating step of separating the process cartridge into the toner developing container and the developing container by disengaging the pins from the process cartridge; (c) a developing roller dismounting step of dismounting the developing roller from the toner developing container separated by the container separating step; (d) a developing blade dismounting step of dismounting the developing blade from the toner developing container separated by the container separating step; (e) a sealing material filling step of filling a sealing material into a gap formed in the toner developing container extending longitudinally inside of an end seal provided at each of longitudinally opposite ends thereof; (f) a developing blade mounting step of mounting the developing blade on the toner developer container having the sealing material; and (g) a developing roller mounting step of mounting the developing roller on the toner developer container having the sealing material.
