摘要： An image forming apparatus includes an electrostatic latent image carrier carrying an electrostatic latent image and a development unit that develops the electrostatic latent image. The development unit includes a developer carrier, first, second, and third developer conveyers, and an opening area. The developer carrier is disposed opposing to the electrostatic latent image carrier. The first developer conveyer supplies a developer to the developer carrier. The second developer conveyer conveys the developer, and transports the developer to the first developer conveyer at a downstream side of the second developer conveyer. The third developer conveyer collects the developer, conveys the developer, and transports the developer to the second developer conveyer in a downstream side of the third developer conveyer. The opening area, disposed higher than a lowermost point of the first developer conveyer, allows the developer to drop from the first developer conveyer to the second developer conveyer.

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.
