Abstract:
A cleaning member includes a core bar, an elastic coating layer, and high-friction coefficient parts provided on both ends of the cleaning member. The high-friction coefficient parts include an elastic material. Outer peripheries of the high-friction coefficient parts are inclined with respect to an axial direction of the core bar. The cleaning member is roller-shaped and is configured to clean a surface of a roller member to be cleaned in contact therewith. A charging device and a process cartridge also include the cleaning member.
