发明名称 ELECTRIC CONDUCTIVE ROLLER, TRANSFER DEVICE, AND IMAGE FORMING APPARATUS
摘要 An electric conductive roller includes a shaft, a cylindrical first elastic body having an electric conductivity and covering the shaft while being in contact with an outer periphery of the shaft, and a second elastic body having an annular shape, disposed at an end portion of the first elastic body, covering the shaft while being spaced apart from the shaft, and having an electric conductivity. The second elastic body has a thickness that gradually increases from a portion between a free end of the second elastic body and a boundary between the second elastic body and the first elastic body to the free end while the second elastic body is retaining an outside diameter greater than or equal to an outside diameter of the first elastic body.
