摘要： An intermediate transfer unit is constructed by covering a conductive cylindrical base member of drum-shape with an elastic member of belt-shape, the elastic member of belt-shape being adhesively fixed to the base member with an adhesive agent, grooves or pits being provided on the surface of the cylindrical base member, the elastic member of belt-shape being adhesively fixed by the adhesive agent filled in the grooves or pits. The adhesive agent has a resistivity smaller than at least the resistivity of the elastic member of belt-shape. By doing so, it is possible to construct and keep the uniform distribution of resistivity without change by environment and deterioration with age, and to realize proper transferring. Furthermore, since the diametrical change of the drum due to uneven application of the adhesive agent can be minimized, the effect on misalignment in color can be minimized.
摘要翻译：中间转印单元通过用带状弹性构件覆盖鼓形的导电圆柱形基底构造，带状弹性构件用粘合剂粘合地固定到基底构件，提供凹槽或凹坑在圆筒形基体的表面上，通过填充在槽或凹坑中的粘合剂将带状弹性构件粘合固定。粘合剂的电阻率至少小于带状弹性构件的电阻率。通过这样做，可以构建和保持电阻率的均匀分布，而不会因环境而变化，随着年龄的恶化，实现适当的转移。此外，由于可以最小化由于粘合剂的不均匀施加引起的滚筒的直径变化，因此可以最小化对颜色不对准的影响。

摘要： An intermediate transfer element has at least one or more elastic layers and a toner releasing layer provided on the surface of the elastic layer and has a surface shape including minute projections up to 60 &mgr;m and at least 20 &mgr;m high. By providing the intermediate transfer element with such projections, easy separation with respect to a poorly separable recording medium, such as thin paper is achieved, and an image free from image defects, such as white speckles.

摘要： A developing apparatus includes toner powder in the form of fine colored powder, a toner carrier, and a frictional controlling member for contacting under a pressure with the toner carrier under pressure to frictionally charge the toner powder and form a thin toner layer on the toner carrier. The toner carrier on which the thin toner layer is formed is rotated so as to transport the thin toner layer to an opposing location on a toner image carrier on which an electrostatic latent image is formed to convert the electrostatic latent image into a visible image. The developing apparatus includes a toner supply roller disposed in rotating contact with the toner carrier at a side of the toner carrier, the frictional controlling member being provided at a position in contact with the toner carrier downstream of the toner supply roller; and a rotatable toner scraping member is provided in a neighboring relationship below the toner supply roller and the frictional controlling member.

摘要： Registration controlling methods are provided for a color electrophotographic apparatus capable of forming an image without color registration errors and uneven color. This is accomplished by preventing a photosensitive medium from being undesirably moved in the direction perpendicular to the transportation direction caused by an electrostatic attractive force between the photosensitive medium and an intermediate transfer device, even if there is a twist between the fixed axis of the member supporting the photosensitive medium and the axis of the member supporting the intermediate transfer device. With these methods, a fur brush cleaner made of a conductive brush is detached from the intermediate transfer device during the time period after the start of driving the photosensitive medium and until the front edge of the photosensitive medium reaches the intermediate transfer device. A small amount of toner therefore always exists between the intermediate transfer device and the photosensitive medium during the transportation of the photosensitive medium, thereby reducing the electrostatic attractive force between the intermediate transfer device and the photosensitive medium and preventing the photosensitive medium from being undesirably moved in the direction perpendicular to the transportation direction. Also during this time period, the photosensitive medium is irradiated by a fade lamp to reduce electric charges on the photosensitive medium.
摘要翻译：为能够形成图像而没有颜色配准误差和不均匀颜色的彩色电子照相设备提供了配准控制方法。这是通过防止感光介质在由感光介质和中间转印装置之间的静电吸引力引起的与传送方向垂直的方向上不期望地移动的，即使在支撑的部件的固定轴之间存在扭转感光介质和支撑中间转印装置的构件的轴线。利用这些方法，在开始驱动感光介质之后的时间段内直到感光介质的前边缘到达中间转印装置，由导电刷制成的毛刷清洁剂从中间转印装置分离。因此，在传送感光介质期间，中间转印装置和感光介质之间总是存在少量调色剂，从而降低中间转印装置和感光介质之间的静电吸引力，并防止感光介质不期望地移动垂直于运输方向的方向。同样在这段时间内，感光介质被褪色灯照射以减少感光介质上的电荷。

摘要： A color image forming apparatus is capable of reducing color deviation of an image due to the influence of a variation in load of an intermediate transfer member and of carrying out high speed printing. A control unit for controlling an image forming process on the basis of the size of a recording medium sets, where a recording medium of a size smaller than the longest image length capable of forming a color image is subject to continuous image formation, a first mode for continuously carrying out a development process for forming a latent image and a toner image, and a second mode of incorporating a stop process for stopping the development process in the midst of the development process. This enables reduction of color deviation of an image caused by the influence of a variation in load of an intermediate transfer member and high speed printing also.

摘要： An image forming apparatus includes a photosensitive belt carried by a driver device, for forming a toner image thereon; an internal transcription belt for transcribing the toner image; and a transcription portion for transcribing the toner image, which is transcribed on the internal transcription belt, onto a recording medium. A transcription side roller is suspended with the internal transcription belt thereon, and disposed on a side of a photosensitive belt side roller. Detectors detect a first cycle of the internal transcription belt, and a second cycle, which starts measurement delaying by ½ cycle of the photosensitive belt side roller from the first cycle measurement start. A controller conducts speed compensation of the photosensitive belt by referring to the first cycle and the second cycle, wherein the internal transcription belt is in contact with the photosensitive belt, so that it is carried following thereafter.
