摘要:
An electrophotographic image carrier is made by depositing an intermediate layer on an electrically conductive substrate and then vapor-depositing, on the intermediate layer, an inorganic photoconductive layer while maintaining the temperature of the substrate during the deposition of the photoconductive layer at a value which is above the melting point of the intermediate layer, but below the damaging temperature of the photoconductive layer.
摘要:
An electrophotographic recording material comprises a photoconductive layer of selenium, selenium compounds, or alloys with selenium, a conductive and flexible substrate, and an intermediate layer between the substrate and photoconductive layer, the intermediate layer being a metal having a modulus of elasticity of less than 6000 kp/mm.sup.2 and a recrystallization temperature of less than 40.degree. C.

摘要:
Electrophotographic recording material composed of a layer of selenium, selenium alloys, or selenium compounds, with arsenic as a additive, disposed on a conductive carrier is given improved properties by forming the layer to have a total arsenic content of 1 to 20%, by weight, and a concentration gradient such that the arsenic concentration decreases from the exposed surface of the layer in the direction toward the carrier and has a concentration of at least 13% at the exposed surface of the layer.
