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。

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 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 use status detecting mechanism includes a cover having an edge portion, in a portion of which a notch is formed, a moving member having a rod member, a spring portion, protrusions and grooves, and a shaft having a driving gear and ribs. In the unused state of a developing unit, the rod member is maintained to be exposed by the contact of the protrusions with the edge portion from the outside. When the developing unit is started to be used and rotation is transmitted to the driving gear, the moving member is rotated by the engagement of the ribs and the grooves, and the moving member is moved to the shaft side by the elastic force of the spring portion when the protrusions are opposed to the notches. Thus, the rod member is retreated from the exposed position.

摘要： A developing device is provided, in which respective lateral ends (the portions overlapped with the side seals 27) of the front seal board 23 are adhered/fixed to the side seals 27. More specifically, the gap between the both sides A1 and the return edge A2 of the opening section A of the toner tank 49 and the developing roller is sealed by a single plane composed of the side seals 27 and the front seal board 23 that are combined with each other. On this account, there is no gap between the side seal 27 and the front seal board 23 due to vibration caused by external force, time degradation etc. (i.e., it prevents the side seals 27 to be away from the front seal board 23). On this account, toner leakage can be securely prevented even when the developing device is driven for a long period of time or when some kind of vibration is applied to the development device.

摘要： A developing apparatus capable of supplying a uniform thin layer of toner and of preventing toner scattering and leakage is provided, where the developing apparatus includes a supply roller for supplying toner to an outer peripheral surface of a toner carrier, the toner carrier for transferring the supplied toner by rotation and a layer thickness controlling member for controlling a thickness of the layer of the supplied toner at a predetermined value while making slide contact with the outer peripheral surface of the toner carrier via the toner, wherein the thin toner layer is supplied to an electrostatic latent image on an image carrier. The layer thickness controlling member is formed of an elastic plate to have a bent portion convex toward the toner carrier. The layer thickness controlling member is held by sealing members so that the bent portion makes elastic contact with the toner carrier outer peripheral surface over a nearly entire length of the toner carrier.

摘要： A cleaning element is arranged on the backside of the toner layer metering blade, i.e., the side opposite to the surface in contact with the developer support, in order to prevent the cleaning element from damaging the blade surface and the abutment surface of the metering blade against the developer support. This cleaning element is frictionally moved across the backside of the toner layer metering blade to remove stuck toner from the toner layer metering blade or prevent occurrence of buildups.
