    • A device applicable to an electrophotographic color copier or a color ink jet printer for selectively supplying visualizing liquids of different colors, e.g. black, red, green and blue or a mixture thereof to a photoconductive drum, paper or like recording medium to form a visible image on the medium which corresponds to an image of an original document. The device includes a black liquid vessel, a red liquid vessel, a blue liquid vessel, and a cleaning liquid vessel. The liquids from the various vessels are selectively fed to the device and, after a visualizing operation or a cleaning operation, selectively returned to the respective vessels by two switching units. Residual toner particles are returned to the black liquid vessel. A purifying member for capturing toner or like visualizing agent which is contained in the black liquid is situated between an overflow port of the black liquid vessel and the other liquid vessels and cleaning liquid vessel. Each of the liquid vessels other than the black and cleaning vessel is provided with an overflow port at a slightly higher level than a liquid level upper limit thereof, an effluent vessel communicating to those overflow ports. Another effluent vessel is communicated to the overflow port of the black liquid vessel.
    • 适用于电子照相彩色复印机或彩色喷墨打印机的装置,用于选择性地供应不同颜色的可视化液体,例如, 黑色,红色,绿色和蓝色或其混合物到感光鼓,纸或类似的记录介质,以在对应于原稿的图像的介质上形成可见图像。 该装置包括黑色液体容器,红色液体容器,蓝色液体容器和清洁液体容器。 来自各种容器的液体被选择性地供给到装置中,并且在可视化操作或清洁操作之后,通过两个开关单元选择性地返回到相应的容器。 残留的调色剂颗粒返回到黑色液体容器。 用于捕获包含在黑色液体中的调色剂等可视化剂的净化部件位于黑色液体容器的溢出口与其他液体容器和清洗液容器之间。 除了黑色和清洁容器之外的每个液体容器都设置有比其液面上限稍高的溢流口,与这些溢流口连通的流出物。 另一个污水容器连通到黑色液体容器的溢流口。

    • A developing apparatus in a transfer-type electrophotographic system having a photosensitive body, wherein the developing apparatus includes a developing roller spaced a small distance from the photosensitive body for supplying a developing solution to the photosensitive body to develop a latent image thereon and to induce a potential on the developing roller through the developing solution from the photosensitive body. A cleaning member is held against the developing roller. In one embodiment, the potential of the developing roller is limited to a level intermediate between predetermined upper and lower limits, and a developing roller is switched into an electrically floating condition except during development of an image. In another embodiment, a developing bias potential is produced responsive to the potential of the developing roller. This bias potential is applied to the developing roller which is used as a developing electrode.
    • 一种具有感光体的转印型电子照相系统中的显影装置,其中显影装置包括与感光体隔开较小距离的显影辊,用于将显影液供应到感光体上以在其上显影潜像,并诱导 通过来自感光体的显影液在显影辊上的电位。 清洁构件被固定在显影辊上。 在一个实施例中,显影辊的电位被限制在预定的上限和下限之间的水平位置,并且除图像显影之外,显影辊被切换到电浮动状态。 在另一个实施例中,响应于显影辊的电位产生显影偏压电位。 该偏置电位被施加到用作显影电极的显影辊。

    • A device for supplying a developing solution in a wet-type electrophotographic copying machine has a scraper pressed against a developing roller positioned in confronting relation to a latent-image carrier or photosensitive drum. The scraper and the developing roller jointly form a space of a V-shaped cross section which serves to form a pool of the developing solution. When the developing roller is rotated, the developing solution is drawn upwardly out of the solution pool and uniformly covers the circumferential surface of the developing roller whereupon it is transferred to the latent-image carrier. The apparatus provides a simple way of eliminating air bubbles from the developing solution before it is applied to the latent-image carrier and for applying the developing solution uniformly to the surface of the latent-image carrier.
    • 用于在湿式电子照相复印机中提供显影液的装置具有一个与潜影载体或感光鼓相对定位的显影辊压紧的刮板。 刮刀和显影辊共同形成V形横截面的空间,用于形成显影液池。 当显影辊旋转时,显影液向上拉出溶液池,并均匀地覆盖显影辊的圆周表面,由此将其转印到潜像载体上。 该装置提供了一种在将其施加到潜像载体之前从显影液中除去气泡并将显影溶液均匀地施加到潜像载体的表面的简单方法。

    • A transfer apparatus is provided of the type in which a toner image formed on a photosensitive member is transferred onto a transfer or copy sheet. The apparatus is used in a copying machine of a so-called delivery type in which the sheet is conveyed using a sheet gripper. During the transfer of a toner image, the appartus applies a corona discharge to the rear side of the sheet which is of the opposite polarity from that of the toner image. The apparatus comprises a diaphragm member for restricting an opening of a transfer charger and disposed between the transfer charger and the photosensitive member, the diaphragm member being movable away from the photosensitive member as the sheet gripper passes between the transfer charger and the photosensitive member.
    • 提供了一种转印装置,其中形成在感光构件上的调色剂图像转印到转印或复印纸上。 该设备用于所谓的传送类型的复印机,其中使用纸张夹持器输送片材。 在转印调色剂图像期间,该配件将电晕放电施加到与调色剂图像相反极性的片材的后侧。 该装置包括用于限制转印充电器的开口并且设置在转印充电器和感光构件之间的隔膜构件,当片材夹持器通过转印充电器和感光构件之间时,隔膜构件可以远离感光构件移动。
