    Abstract: The present invention provides an endless belt superior in peelability even under a low temperature and low humidity environment. An endless belt includes: a first region and a second region, which contain a polyimide-based resin, a contact angle to water of an outer peripheral surface of each of the first region and the second region differing from each other, and a ratio of a sum total of an area of the first region and a sum total of an area of the second region being in the range of about 80:20, to about 20:80.

    Abstract: A full color copying machine which includes intermediate transfer medium whereon toner images having respective color components, formed on a photoreceptor are transferred to form one color toner image, and a screen filter disposed so as to be freely inserted or removed in or from a path of exposure light, which filters the exposure light for exposing the photoreceptor into a pattern of lines. A plurality of color toner images obtained by executing a plurality of copying processes based on a plurality of exposures applied to an original document are superposed on the intermediate transfer medium to form a color toner image. The copying machine further includes a screen mode for inserting a screen filter into a path of exposure light and a normal mode for removing the screen filter from the path of exposure light. Thus, exposures intended for low density components and high density components in an original document image are respectively performed by the use of the different modes, or they are respectively performed by changing setting conditions of the screen filter in the screen mode. With these arrangements, efficient application of the exposure device and high quality of the copied images can be achieved.

    Abstract translation: 一种全彩色复印机,其包括中间转印介质,其中形成在感光体上的具有各自颜色成分的调色剂图像被转印以形成单色调色剂图像;以及筛网过滤器,其被设置为在 曝光光,其过滤曝光光以将感光体曝光成线条图案。 通过基于施加到原始文档的多次曝光执行多个复印处理而获得的多个彩色调色剂图像叠加在中间转印介质上以形成彩色调色剂图像。 复印机还包括用于将屏幕过滤器插入曝光光路径的屏幕模式和用于从曝光光线路径移除屏幕过滤器的正常模式。 因此,分别通过使用不同的模式来分别执行原始文档图像中用于低密度分量和高密度分量的曝光,或者它们分别通过在屏幕模式中改变屏幕滤镜的设置条件来执行。 通过这些布置,可以实现曝光装置的有效应用和复印图像的高质量。
