摘要： In a development device for containing a developer and developing an electrostatic latent image formed on an image carrier, a supplier supplies fresh developer to the development device. A developer carrier carries the developer to be supplied to the electrostatic latent image formed on the image carrier. A plurality of conveyance members conveys the developer contained in the development device in an axial direction of the development device to form a circulation path. An outlet is provided in a wall of a conveyance path formed by one of the plurality of conveyance members and discharges the developer to an outside of the conveyance path. A discharge conveyance member forms a discharge conveyance path to convey the developer discharged from the outlet in the axial direction of the development device and to discharge the developer to an outside of the development device.

摘要： The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the bulk of the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from reaching the level where the recovered developer re-adheres to a developing roller, and further the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from re-adhering to the developing roller.

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.

摘要： An image forming apparatus includes a single support member, an upper body and a lower body. The single support member is positioned between the upper body and lower body and connected at a back lower portion of the lower body. The cumulative weight of the upper body is aligned, to a significant degree, over the location where the support member pushes against the upper body. As a consequence the upper body is conveniently moved away from the lower body when opened, and the gap between the upper body and lower body is free of obstructions so as to facility an operator's ability to perform a maintenance action.
