ABSTRACT:
An electrophotographic photoconductor comprising an electroconductive base and a photosensitive layer formed thereon, the photosensitive layer comprising a selenium-tellurium alloy with a concentration of tellurium in the range of 5 to 20 wt. % and halogen, with a concentration in the range of 5 to 500 ppm, selected from the group consisting of fluorine, chlorine, bromine and iodine, in the photosensitive layer, with the concentration of tellurium substantially uniform or increasing in the direction toward the surface of the photosensitive layer and the ratio of the concentration of tellurium near the electroconductive base to the concentration of tellurium near the surface of said photosensitive layer being 65 or more:100.
