Abstract
A method of remanufacturing a process cartridge includes a step of removing a pin to thereby separate a drum unit and a developing container, a step of separating a developing frame and a developer frame from each other to thereby separate the developing container, a step of resupplying the developer to a developer containing portion of the developer frame, a step of superposing a reseal member on end portion seal members provided at lengthwise one end and other end of a developer supply opening for supplying the developer contained in a developer containing portion to a developing roller, and interposing the reseal member on each of widthwise one end and other end of the developer supply opening along the lengthwise direction of the developer supply opening, and reuniting the developing frame and the developer frame, and a step of reuniting the reconstructed developing container and the drum unit.
