摘要： For realizing a satisfactory and stable developing process, the charge state of a developer and the density of toner particles contained in the developer is kept constant in the developing process. A developing roller to be driven rotationally is provided in a developing tank containing a developer. The developer is sucked magnetically using the magnetic force of a magnet provided in a developing sleeve composing the developing roller. The developer is then fed into a developing area opposed to a photosensitive member, then collected into the developing tank after the developing process is ended. The magnet is composed of an odd number of magnetic poles; developing pole, feeding pole, magnetic force distribution adjusting pole, developer sucking pole, developer separating pole, auxiliary collecting pole, and collecting pole. Between the sucking pole and the developing pole, an even number of poles are disposed. Between the developing pole and the separating pole are disposed an even number of poles. Consequently, the developer used for visualizing an image is separated while it is stuck on the developing sleeve when the developer is separated at the separating pole. When the developer is replaced, sticking of toner on the developing sleeve can be reduced significantly. In addition, the supplied developer is fixed in both toner density and charging level at the developing pole in developing.

摘要： Impurities contained in a developer are captured and prevented from mixing into the developer again, thereby to avoid lowering of image quality due to the impurities. Such impurities include aggregates of the developer formed in a developing apparatus, insufficiently charged toner particles, defectively charged toner particles having an opposite polarity to a predetermined polarity, and defective carrier particles lacking in strength for being held by a developing magnet roller. A recess is provided between peaks of magnetism located in a lower portion of a developing magnet roller. The recess has an air pressure substantially equal to an air pressure (atmospheric pressure) in the developing apparatus, so that air in the developing apparatus and the recess does not flow only in one direction. Impurities contained in the developer circulating around the developing roller cannot be magnetically held in the lower half of the developing roller because of centrifugal force and gravity. Consequently, the impurities are separated and collected in the recess.
摘要翻译：包含在显影剂中的杂质被捕获并防止再次混入显影剂中，从而避免由于杂质而导致的图像质量降低。这样的杂质包括在显影装置中形成的显影剂的聚集体，充足的调色剂颗粒，具有与预定极性相反的极性的缺陷充电的调色剂颗粒，以及由显影磁性辊保持的强度不足的载体颗粒不良。在位于显影磁辊的下部的磁性峰之间设置凹部。凹部的空气压力基本上等于显影装置中的空气压力（大气压），使得显影装置中的空气和凹部不仅在一个方向上流动。由于离心力和重力，包含在显影辊周围显影剂中的杂质不能磁性地保持在显影辊的下半部。因此，杂质被分离并收集在凹部中。

摘要： The invention is characterized by efficiently and quickly loosening an aggregation of toner material formed in a toner cartridge. A toner cartridge has an L-shaped toner agitating member disposed in a main body thereof having a discharge port for feeding toner at the front surface of the main body. Since the toner agitating member is supported so as to pivot like a conical pendulum, a support pin fixed to a bottom surface of the main body passes through a through hole having a greater diameter than that of the support pin. The support pin has an engagement portion attached thereto for prevention of disengagement of the toner agitating member therefrom. A plate-like portion of the toner agitating member defines an agitating plate, a distal end of which extends toward the discharge port of the main body. Shaking the toner cartridge causes the agitating member to rotate about the support pin and to pivot in a direction parallel to the axis of the support pin like a conical pendulum, thereby efficiently loosening the aggregated toner material.
摘要翻译：本发明的特征在于有效且快速地松动形成在调色剂盒中的调色剂材料的聚集。调色剂盒具有设置在其主体中的L形调色剂搅拌构件，其具有用于在主体的前表面供给调色剂的排出口。由于调色剂搅拌构件被支撑成像圆锥摆一样枢转，所以固定在主体底面的支撑销通过直径大于支撑销直径的通孔。支撑销具有附接到其上的接合部分，用于防止调色剂搅拌部件脱离。调色剂搅拌构件的板状部分限定了搅拌板，其远端朝向主体的排出口延伸。摇动调色剂盒使得搅拌构件围绕支撑销旋转并且沿着平行于支撑销的轴线的方向像圆锥摆动一样地枢转，从而有效地松开聚集的调色剂材料。

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 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 developing apparatus comprises a development housing containing developer and disposed opposite to a carrier for carrying a latent image, and a developing roller rotatably provided in the development housing and rotatively driven in a predetermined direction. The developer in the development housing is carried by the developing roller and the developer carried by the developing roller is applied to the carrier through an opening formed in the development housing. A rotation speed F.beta. of the developing roller is higher than a movement speed F.alpha. of the carrier. A gap .beta. between an opening downstream side wall portion of the development housing and the developing roller is greater than a gap .alpha. between the opening downstream side wall portion and the carrier.

摘要： A toner container of the present invention includes a cylindrical portion containing toner used in an electrophotographic type complex machine. When the cylindrical portion is driven to rotate, the toner gets out via an outlet thereof. The cylindrical portion of the toner container has an inner wall provided with a coat layer containing fluorine-containing silica fine particles, which are obtained by modifying a property of the surfaces of silica fine particles by using a fluorine-based silane coupling agent. This coat layer effectively prevents the toner from being adhered to the inner wall of the toner container.
