Abstract:
1. A remanufacturing method for a process cartridge, wherein the process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus, and said process cartridge includes an electrophotographic photosensitive drum having, at one longitudinal end, a drive receiving portion configured and positioned to receive a driving force from the main assembly of the electrophotographic image forming apparatus; a drum frame rotatably supporting the electrophotographic photosensitive drum; a developing frame configured and positioned to support a developing roller configured and positioned to develop a latent image formed on the electrophotographic photosensitive drum; a developer frame accommodating a developer to be used for a developing operation of the developing roller; a first side cover fixed to one longitudinal end of the drum frame and to one longitudinal end of the developer frame; and a second side cover fixed to the other longitudinal end of the drum frame and to the other longitudinal end of the developer frame; an image transfer opening formed along a longitudinal direction of the electrophotographic photosensitive drum for permitting transfer of a visualized image provided by the developing roller onto a recording material; a drum supporting shaft having a flange portion fixed to the drum frame at the other longitudinal end of the drum frame, a first shaft portion inserted into the electrophotographic photosensitive drum, and a second shaft portion extending oppositely from the first shaft portion with the flange portion therebetween and extending through an opening of the second side cover, said method comprising:
