    摘要: A developing device including a supply member pressingly contacted with a toner carrier, wherein the supply member has a hardness which greater than that of the toner carrier. The supply member is rotated in the same direction as the toner carrier to conduct the peeling and supply of toner. A plate spring-like regulation member is pressed against the toner carrier to charge the toner to a predetermined polarity and thin the toner into one or two layers. The toner carrier is made of a foam material.

    摘要: A structure for mounting a rotary member is provided including employing a pair of opposed spaced sheet members. First and second supporting structures are respectively formed at opposed locations on the sheet members, the supporting structures each being one of a projecting part and a barring part. The rotary member is formed with one of an axial shaft or an axial bore on each side thereof for engagement with and support by a corresponding opposed pair of supporting structures. The support structures may be either projecting parts, or barring parts. An image forming apparatus is also provided employing this improved structure for mounting a rotary member. The support structures are formed on frame portions of the image forming apparatus.
