    摘要: A cleaning member has a core member that is freely rotatable, a cleaning material that is spirally wound around an outer peripheral surface of the core member, and holding members. The holding members hold end portions of the cleaning material by the end portions being nipped between the holding members and the outer peripheral surface of the core member. An opening is provided in each of the holding members. Each of the openings is continuously open in line with an axial direction of the core member, and the cleaning material is exposed from the openings.

    摘要: A developing device including a developing roller and applicable to an electrophotographic image forming apparatus is disclosed. The developing roller is made up of a flexible member and a shaft and feeds toner to a latent image formed on a photoconductive element. A supply roller supplies the toner to the developing roller. A gap is formed between the flexible member and the shaft at at least one end portion of a printing region assigned to the developing roller. The gap sets up a uniform pressure between the supply roller and the developing roller and between the developing roller and the photoconductive element.
