ABSTRACT:
A flexible photoreceptor having improved thermal stability and durability and a process for obtaining the photoreceptor by evaporating and condensing selenium-containing photoconductive materials in a profile of increasing arsenic concentration onto a flexible substrate from a plurality of selenium alloy baths of varying concentrations, individually or collectively heated while simultaneously heating and maintaining the temperature of the substrate or interface-substrate layers during evaporation and condensation at no less than the glass transition temperature of the selenium alloy of lowest arsenic concentration to be evaporated from the donor source and not less than about 85.degree. C.
