专利汇可以提供Electrophotographic photoreceptor专利检索,专利查询,专利分析的服务。并且PURPOSE:To enhance the spectral sensitivity and the durability, by vapor-depositing a photoconductive layer, where a specific quantity of doping materials is added to the essential component of microcrystalline silicon, on a conductive supporting material in vacuum and providing a protection layer on this photoconductive layer. CONSTITUTION:A drum base material 11 consisting of Al is put on a supporting table 12 in a reaction vessel 10, and a heater 17 and a work coil 9 are heated with a high frequency to make the inside of the reaction vessel vacuous. Compounding quantities of gaseous SiH4 in a gas bomb 1 which becomes raw materials of Si and B2H6 in a gas bomb 2 and O2, N2, etc. in a gas bomb 3 which become doping raw materials are determined on a basis of the quality design, and flow rates are controlled by valves to introduce them into the reaction vessel through a gas mixer. This gas is decomposed by the glow discharge to form a microcrystalline silicon layer 22 on a substrate 21 of the rotating drum base material 11. A protection layer 23 is provided on the layer 22, thus obtaining an electrophotographic photoreceptor.,下面是Electrophotographic photoreceptor专利的具体信息内容。
