摘要： A developing unit and an image forming apparatus includes drive and control mechanisms for the conveyance of collected toner and fresh toner in an uncomplicated structure and an uncomplicated toner supplying roller structure for the reduction in manufacturing cost. Fresh toner and collected toner stored in housing parts of a toner housing are discharged from an outlet via openings formed in a partitioning member for forwarding to a developing section by a toner supplying roller disposed to confront the outlet. The toner supplying roller is provided in common to fresh toner and collected toner. The toner supplying roller includes a single rotary shaft and a plurality of composite members which are fit into the rotary shaft. Each of the composite members has a cylindrical hollow body and a cylindrical elastic body which is fit onto the outer peripheral surface of the hollow body. The composite members are disposed correspondingly to the housing parts.

摘要： A developing device having a reduced size in the horizontal direction and in which a developing agent is transported with stirring along a circulating route inside a developing tank to effectively mix newly added toner therewith and stir the mixture. A developing tank for storing developing agent therein is horizontally divided with a partition member thereby providing an upper chamber and a lower chamber. A developer roller and a stirring roller are disposed in the lower chamber. Two screw rollers are disposed in the upper chamber. An inlet opening is formed between an end of the partition member and a regulating member for restricting a layer if the developing agent adsorbed to the developing roller. A developing agent removed by the restricting member is fed through an inlet opening to the screw rollers in the upper chamber. The developing agent is mixed with fresh toner supplied through a supply inlet and transported with being stirred by the screw roller in its axial direction. Then, the developing agent is transferred to the screw roller disposed parallel to the screw roller and it is further transported and returned to the stirring roller in the lower chamber through a return port provided opposite to the screw roller. The compact construction of the developing device is realized by arranging screw rollers for stirring and transporting toner in the upper chamber.

摘要： A disk replaying apparatus operates such that the polarity of an FA control signal is serially extracted, and a cycle T is extracted from the polarity. When a reciprocal (1/T) of the cycle T is within a “desired-rotational-speed×0.8

摘要翻译： 磁盘重放装置的操作使得FA控制信号的极性被串行提取，并且从极性提取周期T. 当循环T的倒数（1 / T）在“期望旋转速度x0.8 <1 / T <期望旋转速度×1.2”范围内时，循环T的倒数（1 / T） 设置为转速，否则再次选择循环T. 这种操作归因于固定在一起的盘不完全平行于物镜的绝对位置的事实，使得可以提取对应于盘的旋转的FE信号，并且可以对其响应的FA控制信号 获得。 因此，盘重放装置在转速控制上表现出高的响应性，并且可以以低成本实现。

摘要： A toner cartridge stored in a developer casing includes a biasing force generating device, an actuating rod that switches the biasing device between an active state and a non-active state by one movement of a release member. A developer casing swings by the movement of the actuating rod and presses a developing roller with appropriate pressure to a photosensitive drum. There is a lock member that is restrained from moving by the movement of the actuating rod. The structure recited is capable of inserting and fixing the developer casing to an image forming device. Also, by one restore movement of the release member, the photosensitive drum and the developing roller are separated and the lock is released, thereby enabling removal/exchange of the developer casing.

摘要： A developing unit includes a developing hopper, a toner reserve container that incorporates a replenishing roller and a replenishing port forming a toner replenishing portion, arranged adjacent to the developing hopper in order to supply the toner to the developing hopper. The toner reserve container further includes an agitator rotatable about a rotary shaft and a conveying sheet attached to the agitator for conveying the toner to the replenishing roller. The conveying sheet has a bent portion where the conveying sheet is bent in the rotational direction of the agitator at a halfway point thereof with a predetermined angle &agr;. Deformation of the conveying sheet during rotation is absorbed around the position of the bent portion, so that the conveying sheet will not be plastically deformed at the attached part of the conveying sheet joined to the attachment edge of the agitator, whereby long stable toner conveyance by the conveying sheet can be maintained.

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： The process frame body has the guide portion, and the development device has the to-be-guided shaft. When the process frame body is unattached to the apparatus main body, the guide portion of the development device is absent, thus preventing proper attachment and positioning of the development device. The convex engagement portion is formed integrally with the development device so as to jut into the attachment path for the process frame body. This prevents attachment of the process frame body when the development device is attached first. If users try to attach the process frame body after attachment of the development device, the convex engagement portion interferes with the process frame body, thus preventing attachment of the process frame body.

摘要翻译： 处理框体具有引导部，显影装置具有被引导轴。 当处理框架主体未连接到设备主体时，显影装置的引导部分不存在，从而妨碍显影装置的适当的附着和定位。 凸形接合部与显影装置一体地形成，以便突出到处理框体的附接路径中。 这防止了当首先安装显影装置时工艺框架体的附着。 如果用户在安装显影装置之后试图附着工艺框架体，则凸出的接合部分会干扰处理框体，从而防止工艺框体的附着。

In reproducing multiple fine lines, the line width can be kept uniform in the respective lines and front end chipping or rear end chipping can be prevented, and a high-density and high-quality image can be formed, by comprehensively setting developing conditions so that the relaxation time measured under dynamic conditions in an electric circuit comprising a developing sleeve, a surface of a photosensitive material and a developing layer interposed therebetween is set within a certain range; carrying out the sliding contact between the magnetic brush of the developer and the surface of the photosensitive material so that the frequency of the contact of a carrier with the photosensitive material is set within a certain range; or establishing a specific relation among the rotation number of the developing sleeve, the saturation magnetization of the magnetic carrier and the flux density of magnetic poles in the developing sleeve or further setting the contacting frequency of the carrier within a certain range.
