ABSTRACT:
A developing apparatus includes a developer carrying member for carrying a magnetic developer. The developer carrying member is provided with a plurality of magnetic poles. The apparatus also includes a regulating member for regulating the layer thickness of the developer on the developer carrying member, and an elastic rotatable member, disposed upstream of a developer regulating position of the regulating member with respect to a movement direction of the developer carrying member, for supplying the magnetic developer onto the developer carrying member. A surface of the elastic rotatable member is composed of unicellular foamed material.
