ABSTRACT:
Selenium pellets are produced by compacting, under a pressure, a powdery material selected from a group consisting of powdery metallic selenium, and a mixture of powdery metallic selenium and one or more of additives, and by sintering the resulting compact at a temperature not less than 100.degree. C. but lower than the melting point of selenium.
The selenium pellets are used as selenium source material in vacuum-deposition to produce a photoconductive layer having improved photoelectric properties over those obtained by using conventional particulate amorphous selenium as source material.
