ABSTRACT:
A developing apparatus includes a container for containing a non-magnetic developer and magnetic particles, a developer carrier for carrying the non-magnetic developer toward an image bearing member, a regulating member located adjacent to the non-magnetic developer discharge opening of the container to form a gap between the surface of the carrier and the regulating member, and a magnet positioned adjacent to the carrier at the side of the carrier opposite to the regulating member and causing the magnetic particles to form a magnetic brush upstream of the regulating member adjacent to the developer discharge opening of the container with respect to the direction in which the developer carrier is moved, whereby a thin layer of the non-magnetic developer can be formed on the developer carrier.
