Abstract
A developing apparatus includes a developer bearing member configured to bear a developer on a surface, a regulating member that regulates layer thickness of the developer on the developer bearing member, and a developer conveying member. In addition, a frame has a development chamber in which the developer bearing member and the regulating member are provided, a storage chamber in which the conveying member is provided and the developer is stored, and an opening through which the developer passes into the development chamber. The developing apparatus collects the developer remaining on the developer bearing member into the storage chamber after the developer on the developer bearing member is transferred onto a transfer material. The regulating material includes a step portion that forms a gap between the regulating member and the developer bearing member.
