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： A development apparatus includes three developer conveyance paths with separate functions for the supply, recovery and agitation of a developer, respectively, in which a reduction in size of the apparatus can be achieved. An image forming apparatus includes the development apparatus. By a development region width of a supply opening for delivering developer from a downstream end in the direction of conveyance of an agitation conveyance path to an upstream end in the direction of conveyance of a supply conveyance path and a surplus opening for delivering developer from the downstream end in the direction of conveyance of the supply conveyance path to the upstream end in the direction of conveyance of the agitation conveyance path, a space saving of the upper part of the development apparatus can be achieved and a space saving of the development apparatus as a whole can be achieved compared with a conventional development apparatus.

摘要： A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.
