ABSTRACT:
A developing device includes a developing unit, a developer agitating unit, a developer conveying unit, and a toner supplementing unit. The developing unit develops an electrostatic latent image on an image carrier with a developer containing toner and carrier. The developer agitating unit agitates the developer. The developer conveying unit connects the developing unit and the developer agitating unit, and conveys the developer from the developing unit to the developer agitating unit. The toner supplementing unit is connected to the developer conveying unit, and supplements toner to the developer conveyed from the developing unit to the developer agitating unit.
