    • 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.
    • 显影装置包括显影剂承载构件,显影剂供应,显影剂收集和显影剂搅拌输送路径,转印和交换开口以及分隔。 显影剂承载构件具有双组分显影剂。 开发商供应和开发者收集运输路径分别在第一个方向传达双组分和收集的开发者。 显影剂搅拌输送路径在搅动的同时向第二方向传送多余的和收集的显影剂,以将搅动的显影剂供应到显影剂供给输送路径。 分隔开分隔开显影剂收集,显影剂供应和显影剂搅拌输送路径。 传送口将收集的显影剂从第一方向转移到第二方向。 连通开口设置在显影剂收集输送路径的比第一方向上的转印开口更远的上游侧,并且位于比显影剂收集输送路径更高的位置,使显影剂收集输送路径与显影剂搅拌输送路径连通。
