摘要： One unit type processing unit to be assembled in a laser printer for facilitating replacement work. The processing unit houses therein a photosensitive drum with a part being exposed, a charging unit, a developing unit and cleaning unit. The processing unit is also provided with a flexible protective cover for covering the exposed area of the photosensitive drum when an upper frame of the laser printer is opened. The protective cover can be rolled into a compact configuration and is positioned in a dead space at a position beside the exposed area when the cover is moved away from the exposed area and when the upper frame is closed for printing operation. The rolled cover is stretchable to cover the exposed area when the upper frame is opened.

摘要： An integral type processing unit has a photosensitive drum, a developing unit for forming a developer toner image on the photosensitive drum, and a cleaning unit for scraping off residual toners from the drum. The developing unit does not have sufficient internal volume for accumulating therein the developer toners whose amount meet with the service life of the other components. Therefore, toner containers are replaceably attached to the developing unit for supplementing the developer toners therein. In order to limit the replacement times of the toner containers, each of the toner containers are provided with a segment separable therefrom. Further, a receiving segment is provided at the developing unit engageable with the separable segment. The receiving segment has a predetermined number of receiving portions. If all receiving portions are filled with the separable segments, it becomes no longer possible to further replace the toner container with a new container.
摘要翻译：整体式处理单元具有感光鼓，用于在感光鼓上形成显影剂调色剂图像的显影单元和用于从滚筒刮除残留调色剂的清洁单元。显影单元没有足够的内部体积用于在其中累积其量达到其它部件的使用寿命的显影剂调色剂。因此，调色剂容器可更换地附接到显影单元以补充其中的显影剂调色剂。为了限制调色剂容器的更换时间，每个调色剂容器设置有可从其分离的片段。此外，在可与可分离片段接合的显影单元处设置接收片段。接收段具有预定数量的接收部分。如果所有接收部分都填充有可分离片段，则不可能再用新的容器更换调色剂容器。

摘要： An optical scanning device includes an optical waveguide array through which image information light, scanned by an optical scanning means, is successively introduced and carried. A means for correcting the intensity of light is provided to correct the intensity of the image information light. This correction is performed in correspondence with variations in light transmission efficiency in the optical waveguide. The intensity of light beams on a photosensitive material is, as a result, rendered uniform, these light beams being emitted from the optical waveguide array.

摘要： The present invention provides a configuration in which an electrically connected condition can further be stabilized in electrical-connection zones between a body of an image-forming apparatus, and an image-forming unit and a plurality of image-forming cartridges. Developing electrode members and wire power-feed electrodes are attached to a slide frame. Each of the developing electrode members has a first body-side contact. The developing electrode members are electrically connected with the developing-roller output terminals. The wire power-feed electrodes are electrically connected with wire output terminals through contact with the wire output terminals. The developing electrode members are elastically deformed as a result of their first body-side contacts being pressed in a direction, which is along a slide direction, by the developing-roller output terminals. The wire power-feed electrodes are pressed in a paper width direction by the wire output terminals.
