    • An electrophotographic photosensitive member comprises a drum-shaped or endless-sheet-shaped light-transmissive carrier made of a light-transmissive resin, at least one of the top and bottom surfaces of which has maximum and mean roughness both ranging from 0.3 .mu.m to 4.0 .mu.m, and a photosensitive layer is formed on one of the surfaces of the carrier. The photosensitive layer has a laminate structure composed of a charge generating layer and a charge transporting layer. A light-transmissive layer containing fine particles dispersed in a binder resin may be provided between the light-transmissive carrier and the photosensitive member. An electrophotographic apparatus incorporating this electrophotographic photosensitive member has an image exposure light source such as a laser or an LED array disposed at the side of the photosensitive member adjacent the carrier so as to apply an exposure light to the photosensitive member through the light-transmissive carrier. A facsimile apparatus incorporates this electrophotographic apparatus as a printer.
    • 电子照相感光构件包括由透光树脂制成的鼓形或环形片状透光载体,其顶表面和底表面中的至少一个具有最大和平均粗糙度,范围从0.3μm到 4.0μm,并且在载体的一个表面上形成感光层。 感光层具有由电荷产生层和电荷输送层组成的叠层结构。 可以在透光性载体和感光体之间设置包含分散在粘合剂树脂中的细颗粒的透光层。 包含该电子照相感光构件的电子照相设备具有诸如激光器或LED阵列的图像曝光光源,其设置在与感光体相邻的侧面处,以便通过透光载体向感光构件施加曝光 。 传真装置将该电子照相设备作为打印机。
