Abstract: A vapor-deposited film of selenium as a photoreceptor for electrophotography contains not more than 50 parts per million of oxygen. In producing the film, the oxygen content in the starting material selenium is controlled so that the resulting film contains oxygen within the specified range. The original oxygen content is reduced by vacuum distillation of the material selenium in a high vacuum, reduced-pressure distillation in high purity hydrogen, or preservation of the selenium shot in vacuo or in an inert gas. The starting material is obtained by mixing or melting selenium with a predetermined amount of selenium dioxide, or by carrying out vacuum distillation either of selenium at a vacuum degree of about 10.sup.-2 torr and thereby converting part of the material selenium into selenium dioxide, or of a mixture of selenium and a predetermined amount of selenium dioxide. The vacuum degree during the vapor deposition is controlled so that the oxygen content in the resulting film is 50 ppm or less.

Abstract: A xeroradiographic plate or foil has a non-conducting selenium layer. The X-ray absorption of the selenium layer is improved by additions of elements of high atomic number or chemical compounds of such elements especially lead, thallium and elements of the rare earth group. In a preferred example, the selenium consists of three layers, one layer of pure selenium, a second layer with additions of high atomic number elements and a third layer with an addition of arsenic.
