Abstract:
A developer transporting amount controlling member that is used in a developing apparatus is disclosed. The developing apparatus includes a recording unit having a surface that sustains an electrostatic latent image and attracts a developer, a developer transporting unit that transports the developer, and a developing unit that guides the developer to the recording unit. The recording unit, the developer transporting unit, and the developing unit have rotational center axes that are parallel to each other. The developer transporting amount controlling member includes a magnetic part and a nonmagnetic part that is harder than the magnetic part and is fixed to the developing apparatus such that a portion of the nonmagnetic part is disposed closest to the developing unit.
