摘要： The developing device, which is capable of mixing developers with magnetic toners and capable of providing the developers having a uniform magnetic toner density to a photoconductor for a copying machine, the device having a developing tank which contains a roller composed of a sleeve and a magnetic body with the magnetic body being disposed inside of the sleeve concentrically and rotatably with respect to each other, the device also having a magnetic toner supply tank disposed adjacent to the developing tank for supplying the magnetic toners to the developing tank through a toner supply port, the developing device includes a unit coupled to the developing tank for controlling an amount of the developers to be supplied to the sleeve, and a unit disposed between the toner supply port and the control unit for scraping the developers from the sleeve. The scraping unit is so arranged that a stirring portion is formed in association with the sleeve for stirring the developers scraped from the sleeve and the magnetic toners supplied from the toner supply tank through the toner supply port. The scaping unit has a throughhole for making the scraped developers to be mixed with the magnetic toners supplied from the toner supply tank through the toner supply port in accordance with a magnetic force produced by the magnetic body so as to produce a flow of the developers which passes through the throughhole.

摘要： The length of a conveying sheet is set to be greater than the rotational radius of an agitating element so that the distal end of the conveying sheet will slide over the inner wall of the toner container. A slider element having a low frictional resistance is attached at the distal end of the conveying sheet. The slider element preferably has a low coefficient of dynamic friction and is preferably made of a soft resilient material having a thickness smaller than the conveying sheet. Cutouts or openings may be preferably formed at the distal part. A multiple number of ribs are attached to the wall surface of the toner container at the highest position at which the wall and the top plate meet. The ribs are arranged apart from each other in the direction parallel to the agitating shaft of the agitating element. Each rib is a plate-like element projected inward from the wall surface in the toner container with its width put in the direction of the spacing. Further the end portions of the ribs on the interior side of the toner container are adapted to form a curved surface smoothly connecting the top plate surface and the wall surface.

摘要： A developing unit includes a developer hopper, a toner reserve container that incorporates a replenishing roller and a replenishing opening forming a toner replenishing portion, arranged adjacent to the developer hopper in order to replenish the toner to the developer hopper. The toner reserve container further includes an agitator rotatable about a rotary shaft with a conveying sheet for conveying the toner to the replenishing roller. The conveying sheet is attached to the agitator so that it becomes close to the rotary shaft of the agitator. By this configuration, an adequate space can be secured between the top plate, i.e., an operable/closable lid, constituting the toner reserve container and the conveying sheet so that the distal part of the conveying sheet can efficiently retain the toner, thus making it possible to improve the conveyance performance to the replenishing roller and realize an uniform amount of conveyance.
摘要翻译：显影单元包括显影剂料斗，包含补充辊的调色剂储存容器和形成调色剂补充部分的补充开口，其布置成与显影剂料斗相邻，以便将调色剂补充到显影剂料斗。调色剂储存容器还包括可旋转轴旋转的搅拌器，该搅拌器具有用于将调色剂输送到补充辊的输送片。输送片附接到搅拌器，使得其接近搅拌器的旋转轴。通过这种构造，可以在构成调色剂储存容器的顶板，即可操作/可关闭的盖子和输送片材之间确保足够的空间，使得输送片材的远端部分可以有效地保持调色剂，从而使其可以提高对补充辊的输送性能，实现均匀的输送量。
