ABSTRACT:
A developing apparatus for use in an image forming apparatus includes a developing roller, a developing agent, a refilling port, a transport member, and an agitation enhancer. The developing agent includes toner particles and carrier particles and is refilled to the developing apparatus from the refilling port. The transport member transports the developing agent to the developing roller while agitating the developing agent. The agitation enhancer is provided on a peripheral portion of the transport member to increase agitation movement of the developing agent.
