摘要： An electrophotographic method and apparatus includes a frame having a used toner inlet, a new toner inlet and a combined toner outlet. Opposing sides of the frame are positioned at predetermined angles with respect to a horizontal line extending from a bottom of the frame. The used toner inlet is positioned in an upper portion of the frame next on one of the sides positioned at a predetermined angle, while the new toner inlet is also positioned in the upper portion of the frame, but next to the other side. The predetermined angle of the frame's side that is next to the used toner inlet is at a greater angle than the other side so as to compensate for any degradation in the flow characteristic of the used toner as a result of the recycling process. The frame is configured to interface with a new toner bottle having an opening that cooperates with the new toner inlet. Accordingly, when the new toner supply is exhausted, the new toner bottle may easily be replaced without having to remove any other components.
摘要翻译：电子照相方法和装置包括具有用过的调色剂入口的框架，新的调色剂入口和组合的调色剂出口。框架的相对侧相对于从框架的底部延伸的水平线定位成预定角度。所使用的调色剂入口位于框架的上部，接着位于以预定角度定位的一侧上，而新的调色剂入口也位于框架的上部，但是位于另一侧。与废旧调色剂入口相邻的框架侧的预定角度比另一侧更大的角度，以便补偿由于再循环过程而导致的二手调色剂的流动特性的任何劣化。框架被配置成与具有与新调色剂入口配合的开口的新墨粉瓶接合。因此，当新的调色剂供应被排出时，可以容易地更换新的调色剂瓶，而不必去除任何其它组分。

摘要： An image forming apparatus of the present invention includes a charging device made up of a charge roller and a roller cleaning member for cleaning the charge roller. The charge roller is held in contact with a photoconductive element and uniformly charges the element while being driven by the element. The roller cleaning member is held in contact with the charge roller in order to remove impurities from the roller. The charge roller has a resistance ranging from 1.times.10.sup.3 .OMEGA. to 1.times.10.sup.7 .OMEGA.. The cleaning device exhibits a stable charging ability over a long time of use without resorting to a mechanism for moving the charge roller into and out of contact with the photoconductive element or for moving the roller cleaning member into and out of contact with the charge roller.

摘要： An image forming apparatus whereby it is possible to prevent unevenness in developing density caused by misalignment between the central axes of a driven side rotational coupling section for rotating a developer carrier and a drive side rotational coupling section for transmitting rotational drive force to the driven side rotational coupling section. The driven side rotational coupling section is fixed and the position thereof can be corrected slightly, by engaging the driven side rotational coupling section with a drive side rotational coupling section. A transmission gear is provided which meshes with the driven side rotational coupling section and transmits rotational drive force used to move the surface of the developer carrier. By means of an axle provided on at least one end of the transmission gear engaging with a positioning member on the main body of the image forming apparatus, the developer carrier is positioned in the main body of the image forming apparatus.

摘要： A development device including a developer container, a developer bearer, a magnetic field generator, a developer agitator to supply the developer to the developer bearer, and a developer regulator to adjust a layer thickness of the developer carried on the developer bearer. Multiple oval recesses oblique to the axial direction of the developer bearer are formed in the outer circumferential surface of the developer bearer and arranged in a circumferential direction and the axial direction thereof. An upstream inner wall of the recess in the rotational direction of the developer bearer applies a force to the developer as the developer bearer rotates, and an angle between a long axis of the recess and the axial direction is set so that the force applied by the upstream inner wall of the recess has a component in a direction substantially identical to the developer conveyance direction of the developer agitator.

摘要： To downsize a developing device in the developing carrier axial direction without generating image concentration irregularities from recirculation of developer in the magnetic roller end regions, an N2 pole and an N3 pole, which are mutually adjacent having the same polarity (N polarity), and which are for generating a magnetic force for removing from a developing sleeve a developer that has passed through a developing region, are provided on a magnetic roller. Magnets of this developing device, which are for generating a magnetic field to displace to the inside in the axial direction magnetic force lines that cause peeling force in the direction of separation from the developing sleeve to act on developer on the developing sleeve, based on the magnetic force of the N2 pole and the N3 pole, and that pass through the axial direction end regions within a developer separation region on the developing sleeve, are provided on the outside of the magnetic roller.

摘要： A developing unit includable in a process cartridge and in an image forming apparatus includes a developer bearing member including a magnetic field generator and a nonmagnetic hollow member, a developer container, an agitation/conveyance member, and a developer regulating member. The magnetic field generator has first and second magnetic poles to generate respective magnetic forces for removing the developer from the developer bearing member after the developer passes the development region. A developer-releasing region releases the developer from the developer bearing member using a release force. The developer is disposed higher than a surface of the developer in the developer storing chamber. A component of a magnetic flux density of the magnetic field generated by the magnetic field generator in a direction normal to the developer-releasing region is directed to a same direction as the first and second magnetic poles across the developer-releasing region without forming a local maximum point.
