摘要： A developing device capable of preventing deterioration of the image quality, which is caused when a developer recovered by a developing roller re-adheres thereto, and an image forming apparatus equipped with the developing device. 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 amount of developer existing on the upstream side of the agitation conveyance path in the developer conveyance direction becomes small, whereby the developer can be delivered smoothly from the recovery conveyance path to the agitation conveyance path. Therefore, 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.
摘要翻译：一种能够防止由显影辊回收的显影剂重新附着的显影剂的图像质量劣化的显影装置和配备有显影装置的图像形成装置。在显影剂输送方向上的搅拌输送路径的上游侧的显影剂输送量比通过将回收输送路径向搅拌输送路径输送的显影剂的量变大，显影剂输送方向上的搅拌螺杆等于或大于在显影剂输送方向上的回收螺杆的下游侧的显影剂输送量。因此，显影剂输送方向上的搅拌输送路的上游侧的显影剂的量变小，能够使显影剂从回收输送路径平稳地输送到搅拌输送路径。因此，可以防止在显影剂输送方向上在回收输送路径的下游侧存在的显影剂的体积达到恢复的显影剂重新粘附到显影辊的水平，并且进一步存在于下游侧的显影剂可以防止显影剂传送方向上的恢复传送路径再次粘附到显影辊上。

摘要： A developing unit containing developer including carrier and toner and developing a latent image formed on an image carrier is disclosed. The developing unit includes multiple conveyor members configured to convey the contained developer in respective longitudinal directions so as to form a circulation channel; a supply part configured to supplement the carrier in the developing unit; a discharge part configured to discharge a first part of the contained developer outside the developing unit; and a bypass channel configured to cause a second part of the developer to return to the upstream side of the circulation channel without passing a position where the discharge part is provided.
