Abstract
A synthetic resin part connecting member connects at least two injection molded pieces that can be used as frames for a process cartridge detachably mountable on an image forming apparatus. The molded pieces are set in dies different from the dies used for forming the molded pieces, and a molten resin is injected into a gap formed between opposed surfaces of the molded pieces. An injection channel for the molten resin up to the gap is formed in one of the molded pieces. A rib for stopping resin is provided in the injection channel to stop the flow of the molten resin injected into the injection channel.
