摘要： An endless flexible seamed belt with a mechanically and electrically invisible seam, substantially equivalent in performance to a seamless belt, is formed by joining two ends of substrate material, each end of which has a plurality of mutually mating elements in a puzle cut pattern which are in interlocking relationship. After the two ends are joined, an bonding is applied to the seam of the belt. When the belt is to be an electrostatographic imaging member, the electrostatics of the belt become very important. The two ends of a flexible substrate with a conductive coating applied thereto are interlocked and a conductive bonding is applied to the gap between the interlocking surfaces. The undercoating layer can then be applied to the adhered seam in order to smooth the seamed surface for application of the charge generating layer and the charge transfer layer. The undercoating layer may be relatively thicker than current undercoating layers to insure that the seam surface is smooth.
摘要翻译：通过连接基材材料的两个端部形成一个具有机械和电学不可见的接缝的无缝柔性缝合带，其基本上等同于无缝带，性能相当于其中每个端部具有多个相互匹配的元件，其中pizle切割图案是互锁关系。在两端连接之后，将粘合施加到带的接缝上。当皮带成为静电成像构件时，皮带的静电变得非常重要。具有施加到其上的导电涂层的柔性基板的两端互锁，并且在互锁表面之间的间隙上施加导电接合。然后可以将底涂层施加到粘附的接缝上，以平滑接缝表面以施加电荷产生层和电荷转移层。底涂层可以比当前的底涂层相对更厚，以确保接缝表面光滑。

摘要： A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 10 to about 75 percent by weight of: ##STR1## The above compound has the chemical name bis(4-diethylamino-2-methylphenyl)-4-diphenylaminophenyl methane. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
