Abstract

A remanufacturing method includes dismounting, from one end of a drum frame, a supporting member while rotatably supporting one end of a drum and a developing device frame; separating the two frames; dismounting the drum; mounting one end of a fresh drum to the other end of the drum frame; a refilling developer into a developer accommodating portion of the separated developing device frame; and swingably connecting the developing device frame and the drum frame by mounting the supporting member to one end of the drum frame, while rotatably supporting, by the supporting member, the one end of the drum of the drum frame to which the fresh drum has been mounted and swingably supporting the one end of the developing device frame to the developer accommodating portion of which the developer has been refilled, by the drum frame.

Description

technical field [0001] The present invention relates to a method for remanufacturing a process cartridge detachably mountable in a main assembly of an electrophotographic image forming apparatus. Background technique [0002] In the specification of the present invention, a process cartridge refers to a cartridge in which an electrophotographic photosensitive drum and at least a developing device among various devices for processing the photosensitive drum are integrally installed, and the cartridge can be detachably installed in an electrophotographic image forming system. in the main component of the device. [0003] An electrophotographic image forming apparatus refers to an apparatus that forms an image on a recording medium by using an electrophotographic image forming method. As examples of electrophotographic image forming apparatuses, electrophotographic copiers, electrophotographic printers (LED printers and laser printers, etc.), facsimile apparatuses, word proces...
