MANUFACTURE OF VAPOR DEPOSITION SOURCE SELENIUM MATERIAL OF PHOTOSENSITIVE LAYER

PURPOSE:To obtain a vapor deposition source Se material for forming a photosensitive layer good in repeating fatigue resisting characteristics by distilling the Se material specified in compsn. in vacuum, condensing it in an inert gas atm., remelting it, and dropping it into water to form granules. CONSTITUTION:An Se material having a specified compsn., such as Se-Te alloy, is distilled in vacuum, the obtained molten material is collected and condensed in an amt. of inert gas, such as N2, to form ingots. They are heated again in the inert gas atm. to melt them, and dropped into waer to form granules, thus manufacturing the intended vapor deposition source Se material. The electrophotographic sensitive body of Se obtained by vapor depositing this material on a conductive substrate is not deteriorated in copied image quality even by repeated uses, and it can form always sharp images.
