装置。 A developer carrier that conveys a monocomponent developer to the surface of the electrostatic latent image carrier, a supply member that supplies the monocomponent developer to the developer carrier, and a developer carrier that supplies the monocomponent developer to the developer carrier. In a developing device for a one-component developer comprising a developer applying member that forms a constant thin layer of developer, the developer applying member is uniaxially supported so as to be placed on an upper surface of a developer carrier. and a biasing force applying means, which applies a biasing force to one end of the coating body in response to a development start signal and releases the biasing force in response to a development end signal,
A developing device for a one-component developer, characterized in that upon completion of development, the developer located between the upper surface of the developer carrier and the application body of the developer application member is removed.
