摘要： A developing device which can stably supply a developer to a latent image carrier by preventing the scattered developer from being discharged and thereby preventing the developer from being discharged despite that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw serving as a developer conveying member moves toward a developer discharge port. Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.

摘要： A development device includes a developer carrying member, developer supply, developer collection and developer agitation conveyance paths, transfer and communication openings, and partition. The developer carrying member bears a two-component developer. The developer supply and developer collection conveyance paths respectively convey the two-component and collected developers in the first direction. The developer agitation conveyance path conveys excess and collected developers in a second direction while agitating to supply the agitated developers to the developer supply conveyance path. The partition separates the developer collection, developer supply, and developer agitation conveyance paths. The transfer opening transfers the collected developer from the first to the second direction. The communication opening, disposed at a further upstream side of the developer collection conveyance path than the transfer opening in the first direction and at a higher position than the developer collection conveyance path, communicates the developer collection conveyance path with the developer agitation conveyance path.
