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 detection mechanism is provided with a sealing member made of elastic material for preventing toner leakage between (a) a pierced wall surface of a toner tank through which a rotating shaft is inserted and (b) a second side plate provided on the rotating shaft. With this structure, a flat splicing surface of the sealing member is made to closely contact a second side plate that can be coated with a high lubricant member whose frictional forces is small. When a sealing force of the sealing member is strongly compressed, the sealing member prevents toner from coming into the sliding surface.

摘要： Elastic members are fixed at one end to the housing of an image forming apparatus while their distal ends extend into the framework of the developing unit. When a toner cartridge is fitted to the framework of a developing unit, the distal ends of the elastic members abut the top surface of the toner cartridge, so that the elastic members are compressed to produce repulsive force, which in turn causes the developing unit to rotate clockwise about a support so as to bring the developer roller into pressing contact with a photoconductor.

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.
