Abstract
The present invention provides a method for recycling a process cartridge removably mountable to an image forming apparatus, comprising the steps of: (a) dividing a process cartridge into a first frame including an image bearing member, and a second frame including a developing means and a developer containing means for containing developer used by the developing means and having an opening through which the developer is supplied to the developing means; (b) thereafter, removing the developing means from the second frame; (c) thereafter, replenishing developer to the developer containing means through the opening; (d) thereafter, removably attaching a seal for closing the opening to the opening; and (e) thereafter, locking the first and second frames to each other, thereby assembling the process cartridge.
