摘要： When the upper case of the developing device is pushed from above, the upper case may be deformed producing a negatively activated pressure corresponding to the deformed volume of the case, thereby dispersing toner along with the air. When the developing device is mounted to or dismounted from the color image forming apparatus, the dispersed toner may fall out of the developing device. To prevent the toner from falling out of the developing device, the toner carrier and the limiting member for limiting the toner layer thickness are held in the developer case and a falling toner receiver is formed which is recessed in the developer case in the longitudinal and widthwise directions of the toner carrier and the limiting member for limiting the toner layer thickness. The falling toner is collected in the receiver, preventing the device from being contaminated with the falling toner and facilitating the cleaning of the device.
摘要翻译：当从上方推动显影装置的上壳体时，上壳体可能变形，产生与壳体的变形体积相对应的负激活压力，从而与空气一起分散调色剂。当显影装置安装到彩色图像形成装置上或从彩色图像形成装置上卸下时，分散的调色剂可能从显影装置中脱落。为了防止调色剂从显影装置中脱落，调色剂载体和用于限制调色剂层厚度的限制部件被保持在显影剂盒中，并且形成一个下落的调色剂接收器，其在纵向和横向方向上凹进显影剂盒中调色剂载体的方向和用于限制调色剂层厚度的限制构件。落下的调色剂被收集在接收器中，从而防止设备被落下的墨粉污染并便于清洁设备。

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.

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.
