摘要： 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.

摘要： A developer-remaining-amount notifying device for notifying a remaining amount of a developer accommodated in a developer accommodating unit and used for developing a latent image formed on an electrophotographic photosensitive member is provided. The device includes a position detection member positionable near an upper surface of an accumulated layer of the developer accommodated in the developer accommodating unit, a regulating member, and a notification device. The regulating member regulates a moving direction of the position detection member such that the position detection member moves substantially linearly in accordance with a gradual decrease of the developer accommodated in the developer accommodating unit as the developer is used for development. The notification device notifies a remaining amount of the developer accommodated in the developer accommodating unit in accordance with a position of the position detection member.

摘要： A cleaning device for an image forming apparatus such as an electrophotographic copying machine wherein the cleaning device is usable for removing toner from a photosensitive member. The cleaning device is effective to provide a solution to the problem caused by the toner particles and other foreign matter gripped between the cleaning member and the photosensitive member. According to this invention, the problems are solved by controlling the manner of bringing the cleaning member into contact with the photosensitive member and/or the manner of bringing the same out of contact.
