摘要： The present invention relates to an electrophotographic sensitive member for use in a laser line printer.A laser line printer using a laser beam as a recording member has been known for a small-sized, light, low power consumption, high-density and high-speed recording method. For example, a semi-conductor laser printer and an electrophotographic sensitive member mainly formed of amorphous silicon used therein are being watched with interest.However, since this laser beam is monochromatic, a laser beam incident upon the inside of a photosensitive layer is very much inclined to be not sufficiently absorbed by the photosensitive layer to reach an electrically conductive substrate and be reflected at the surface of the electrically conductive substrate.With a photosensitive member having a photosensitive layer laminated on an electrically conductive substrate, there has been a problem in that a part of an incident ray such as a semiconductor laser ray is reflected by the electrically conductive substrate and if a part of this reflected ray is reflected by the surface of the photosensitive layer again, an interference occurs between this twice reflected ray and the incident ray to produce an interference fringe on a charge latent image whereby an interference fringe-like concentration unevenness on the image after developing.The present invention was achieved in order to eliminate the above described problem and it is an object of the present invention to provide an electrophotographic sensitive member, in which a photosensitive layer having at least a photoconductive layer is laminated on an electrically conductive substrate and a laser beam is incident upon a surface side of said photosensitive layer to generate an optical carrier in said photoconductive layer, characterized by that an interference of an laser beam can be reduced to prevent a stripped pattern from generating on an image by forming said photosensitive layer on said electrically conductive substrate through an intermediate layer and selecting a .times.b.sup.2 .times.c of 0.2 or less, wherein a is a transmission factor of said laser beam through said photosensitive layer, b being a transmission factor of said laser beam through said intermediate layer, and c being a reflection factor of said laser beam by said substrate.

摘要： The invention relates to improvements in an electrophotographic sensitive member having a photoconductive layer formed with amorphous silicon produced by glow discharge decomposition or sputtering. An electrophotographic sensitive member is formed by laminating an amorphous silicon barrier layer and an amorphous photoconductive layer successively on an electrically conductive substrate, the first mentioned layer containing an impurity of Group IIIa of Periodic Table of Elements, or nitrogen and impurity of Group IIIa of same Table, and also containing oxygen within a range of 0.1 to 20.0 atomic % at the point of the layer and in a progressively decreasing pattern throughout the rest thereof. Constructed as such, the photosensitive member has an increased photosensitivity to near-infrared beams, a large charge-holding capability, and low-rate dark attenuation characteristics. In addition, it is less expensive to manufacture.

摘要： An electron tube cathode has a composite suppression layer structure interposed between the base metal and the electron-emitting material to suppress an interface layer formed through the reaction of the base metal with the electron emissive material. The composite layer structure includes a thin layer of Pt or Re and a layer of oxide of Zr and/or Hf. As a result, the formation of the interface layer is prevented so that the useful life of the electron tube cathode is prolonged.
