Developing unit and process cartridge

摘要

The present invention relates to a developing unit including a developer bearing member configured to bear a developer, the axis of the developer bearing member being inclined with respect to the axis of an image bearing member. The developing unit includes a developer accommodating chamber that accommodates the developer; and a conveying member provided in the developer accommodating chamber and supplying the developer from the developer accommodating chamber to the developer bearing member by rotation. The axis of the conveying member is inclined with respect to the axis of the developer bearing member. The developer conveying force of the conveying member differs depending on the position in the axial direction thereof and increases as the distance from the axis of the conveying member to the surface of the developer bearing member increases.
