Abstract:
A developing apparatus, includes: a developer bearing member that encloses a magnet roller having a plurality of magnetic poles and is rotatable; a wall that forms a developer storing chamber for storing a magnetic developer therein; a restricting member configured to restrict a layer thickness of the magnetic developer carried by the developer bearing member; and a moving member configured to move the magnetic developer carried by the developer bearing member before the magnetic developer is restricted by the restricting member, the moving member being brought into contact with a surface of the developer bearing member, the moved developer being on the developer veering member after the moving member moved the developer on the developer bearing member, wherein the moving member is disposed at a position opposed to any of the magnetic pole positions of the plurality of magnetic poles.
