Abstract
A remanufacturing method for a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the process cartridge including a first unit supporting an electrophotographic photosensitive drum and a second unit supporting a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum and having a developer accommodating portion accommodating a developer to be used for development of the electrostatic latent image by the developing roller, the first unit and the second unit being rotatably coupled, the method including (a) a unit separating step of separating the first unit and the second unit from each other; (b) a developer filling step of filling the developer into the developer accommodating portion of the second unit; (c) a unit coupling process of coupling the first unit and the second unit with each other; and (d) a tape affixing step of removably affixing a tape along an outer surface of the first unit, an outer surface of a drum shutter for covering such a portion of the electrophotographic photosensitive drum which is exposed from the first unit and a second unit, an outer…
