A method for vacuum depositing a selenium-arsenic coating on a substrate to form a photoreceptor by evaporating selenium with an arsenic concentration of 0.1 to 0.6 percent by weight and discontinuing the evaporation when the weight of the selenium alloy remaining is 2-10 percent of the original weight.

Process for manufacturing an improved selenium alloy x-ray imaging

A selenium alloy electrophotographic imaging member having an optically transparent NESA coated substrate. An x-ray image is formed from the side of the photoreceptor opposite the transparent substrate and then is scanned from the back side through the transparent substrate with a fine beam of light, the position of which is precisely monitored. The ensuing discharge from the light beam is detected by a non-contacting x-ray transparent electrode located on the outer side of the photoreceptor, away from the substrate, which reads the discharge signal through capacitive coupling, pixel by pixel, according to the position of the light beam, to form a high resolution raster pattern digital readout of the image.
