    摘要: A cleaning device is disposed substantially vertical above a photosensitive drum for the purpose of constructing a compact electrophotographic printer. The cleaning device includes a housing that accommodates an auxiliary toner conveying part and a sheet-like resilient member. A cleaning brush is also disposed in the housing so that a gap of 1-3 mm is formed between the cleaning brush and the auxiliary toner conveying part and resilient member. During an image forming operation, toner accumulates between the cleaning blade and the cleaning brush and is conveyed upward through the gap between the cleaning brush and the auxiliary toner conveying part and resilient member. The toner drops onto the cleaning brush near the top thereof and is conveyed by the cleaning brush to a screw. The screw discharges the toner from the cleaning device.

    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 device, process cartridge, and image forming apparatus, include at least one developing roller. A plurality of transport members with screw and shaft portions, transport developing agent housed within the device in a longitudinal direction, and form a circulation path. A discharge aperture, formed in a transport path wall of one transport member, discharges developing agent to the outside when a surface of the developing agent transported by one of the plurality of transport members exceeds a predetermined height. The one transport member is adjacent to the developing roller that supplies the developing agent and includes, in a part in the longitudinal direction, an area on which the screw portion is not formed. The discharge aperture is disposed opposite to the area on which the screw portion is not formed, and the length of the discharge aperture is formed smaller than that of the area in the longitudinal direction.

    摘要: A developing device, process cartridge, and image forming apparatus, have transport members with screw and shaft portions, transporting developer within the device in a longitudinal direction of a circulation path. A supply supplies new carrier to the device. A discharge aperture in a transport path wall of one transport member discharges developer outside the circulation path, when a surface of the developer transported by the one transport member exceeds a predetermined height. A bias path aperture in the transport path wall upstream of the discharge aperture has a bottom at a higher level than a bottom of the discharge aperture, and diverts developer at a level higher than the bottom of the discharge aperture to another transport member. An area in the longitudinal direction of the one transport member has no screw portion, and the discharge aperture is disposed opposite the area and has a length smaller than the area.

    摘要: A premixed developing system developing device, process cartridge, and image forming apparatus, in which a developing agent thrown up by a transport member is not discharged from a discharge aperture, variation in the quantity of the developing agent discharged to the outside does not occur, and the image quality of images output is stable. A discharge aperture is formed in the wall of a transport path of a transport member to discharge the developing agent to the outside when the surface of the developing agent exceeds a predetermined level. The transport member is provided with an area, in a part in the longitudinal direction, in which a screw portion is not formed. The discharge aperture is disposed opposite to the area, where the screw portion is not formed on the transport member, and is formed such that the length of the discharge aperture is smaller than the length of the area in the longitudinal direction.
