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： An imaging device provided with a latent image carrying body rotatably disposed to carry a latent image, a developing unit that develops the latent image carried on the carrying body by using a developer containing toner at least, and a duct disposed downstream of the developing unit and having a wall with an upstream suction port and a downstream suction port formed. An air flow path is formed by a surface of the latent image carrying body and a surface of the duct wall, between the upstream suction port and the downstream suction port. A gap of the air flow path is wider at the downstream side than at the upstream side with respect to the rotational direction of the latent image carrying body.

摘要： A developer supply system includes a container, a memory, and a positioning mechanism. The container has a deformable bag formed of flexible material to accommodate developer therein. The memory is attached to a given planar surface of the deformable bag to store information for communication to the image forming apparatus. The positioning mechanism holds the container therein while maintaining the given planar surface in position relative to the image forming apparatus when the deformable bag collapses as it discharges developer. An image forming apparatus employing such a developer supply system is also disclosed.

摘要： A powder filling method, which fills at least two kinds of powders with different specific gravities into a powder container, and by which a region having only a powder with the highest specific gravity out of the at least two kinds of powders is prevented from being generated in the filled powder container. A toner, which is a first powder that does not include a carrier having the highest specific gravity, is mixed with air in a toner storage portion. The air is introduced into the toner particles to increase the bulk of the toner, and then a toner filling device fills a toner bottle serving as the powder container with the toner having the air. Upon completion of such filling, a carrier filling device starts filling the carrier, which is a second powder, into the toner bottle. Filling of the carrier is completed before the air is released from the toner particles contained in the toner bottle and thereby the bulk of the toner is reduced and then stabilized.
