摘要： In an image forming apparatus, a developing device is disposed adjacent to a belt-like photosensitive member. A rotary type developing device has a hollow cylindrical casing rotatable around a shaft having a central portion for rotation. The developing device includes a casing which is rotated in a predetermined direction, and four partitions which divide the casing to make four developing units which extend radially outward from the shaft. A toner storing section or hopper is provided on one side of the developing device, i.e., on a front side of the image forming apparatus, and a toner cartridge is detachable from a top of the hopper, and the toner cartridge is exchanged when an end signal of the toner is detected by a sensor in the casing. The toner hopper is filled by new toner from the toner cartridge, and the toner is carried by conveyor members, which control an amount of the toner in the casing, and a supply roller supplies the toner to a developing roller. Therefore, the device supplies a required amount of toner to a toner supply roller and a developing roller at all times. This provides an image forming apparatus with a great freedom of layout which needs a minimum sectional space relative to a photoconductive element and which, therefore, has a miniature configuration. Also, if amounts of transport of first and second conveyor members are adequately selected, a uniform developer distribution in a longitudinal direction without resorting to a complicated control is insured.
摘要翻译：在图像形成装置中，显影装置邻近带状感光构件设置。旋转型显影装置具有中空圆筒形壳体，该中空圆柱形壳体可围绕具有用于旋转的中心部分的轴旋转。显影装置包括沿预定方向旋转的壳体和分隔壳体以形成从轴径向向外延伸的四个显影单元的四个隔板。调色剂存储部分或料斗设置在显影装置的一侧，即在图像形成装置的前侧，并且调色剂盒可从料斗的顶部拆卸，并且调色剂盒在末端调色剂的信号通过壳体中的传感器检测。墨粉盒由调色剂盒中的新调色剂填充，调色剂由传送部件承载，传送部件控制壳体中的调色剂量，供给辊将调色剂供给显影辊。因此，该装置始终向调色剂供应辊和显影辊提供所需量的调色剂。这提供了一种具有很大布局自由度的图像形成装置，其需要相对于光导元件的最小截面空间，因此具有微型构造。此外，如果适当地选择第一和第二输送器构件的输送量，则不会诉诸于复杂的控制，所以在长度方向上均匀的显影剂分布被保证。

摘要： A joint having an OLDHAM state coupling at a leading edge thereof is held movably in a direction which is parallel to a joint axis at a full-color printer body. A coupling gear is substantially connected to a developing roller disposed in each mono-color developing unit, which makes up a revolving type developing device. At the time of developing by one of the mono-color developing units, the joint is capable of moving in parallel to the axis of the joint in the state of being rotated toward the coupling. A projection is further provided at the leading edge of the coupling, and a claw is further provided at the end of the coupling gear. Thereby, smooth engagement between the coupling gear and the coupling is made by the help of the OLDHAM state coupling, the projection and the claw. As a result, the driving force is transmitted from the joint to the developing roller disposed in the developing unit, so that the developing roller can rotate at a predetermined speed and direction.

摘要： In an image forming apparatus, a rotary developing device effects development by revolving a plurality of developing sections around a rotary shaft until any one of them reaches a developing position where it faces an image carrier. Cartridges are respectively mounted to hoppers included in the developing sections. Guides are provided on the inner periphery of each cartridge in order to guide toner, moving due to the revolution or the developing device, toward a toner outlet formed in the cartridge. Even when the amount of toner remaining in the cartridge is small, the entire toner is replenished into the associated hopper and fully consumed.

摘要： A revolver type developing device for an image forming apparatus. A rotary body is mounted on a shaft and has a plurality of developing units mounted thereon. The developing units are arranged around the shaft, and each stores a powdery developer and accommodates a developer transport member for supplying the developer to an image carrier. A drive source rotates the rotary body to bring any one of the developing units to a developing position where the developing unit faces the image carrier. A one-way transmission mechanism is located on a drive transmission path extending from the drive source to the rotary body for preventing a drive force from being imparted from the rotary body to the drive source. When the rotary body tends to rotate or vibrate due to an external force or vibration, the rotation or vibration is prevented from reaching the drive source.

摘要： In an image forming apparatus, a revolver type developing device has a plurality of developing units and revolves to sequentially bring them to a developing position facing an image carrier on which a latent image is electrostatically formed. The revolver promotes easy replacement and safe handling of the developing units and can be accurately positioned relative to the body of the image forming apparatus. Despite that the revolver is miniature, it prevents developers from leaking or flying off from the developing units and contaminating the inside of the apparatus or being mixed with each other.

摘要： A developing device capable of obviating the cohesion of toner and reducing the amount of dead toner is disclosed. The device has a developing unit accommodating a first and a second screw therein. The first and second screws extend from the toner hopper to the other longitudinal end of the developing unit in parallel to a developing roller and a supply roller. The first screw feeds toner from a toner hopper to a developing section. The second screw collects toner not contributed to development from the developing section and returns it to the first screw for recirculation. In this configuration, the collected toner and dead toner aggregating in the lower portion of the developing unit are forcibly moved to the developing section. The direction in which the screw portion of the second screw is inclined may be partly reversed to form a reverse transfer portion. Alternatively, a part of a casing adjoining the hopper may be implemented as a slant. The reverse transfer portion or the slant recirculates the toner more forcibly.

摘要： A color image forming apparatus of the type having a photoconductive belt for forming a latent image thereon electrostatically. The latent image is developed to turn out a corresponding toner image. The toner image is transferred from the photoconductive belt to an intermediate transfer belt. Such a procedure is repeated to form a composite color image on the intermediate belt. The color image is transferred from the intermediate belt to a recording medium. Any point on the intermediate belt in the direction of rotation and any points on drive rollers assigned to the two belts, respectively, in the direction of rotation are held in the same positional relation to a stationary member every time the intermediate belt completes one rotation.
