Abstract

A photoreceptor having sensitivity to infra-red to approximately 875 nm is disclosed comprising a polymeric substrate, an overlying layer of conductive film, an optional polymeric adhesive layer, a hole transport layer, a selenium-tellurium alloy layer and a polymeric overcoating. The selenium-tellurium a1 loy functions as a generator layer and may be prepared by vacuum depositing a layer having a thickness of between about 0.3 micrometer and about 2 rnicrometers and containing between about 20 weight percent to about 45 weight percent tellurium. The hole transport layer rnay be of any suitable material such as a diamine molecule dispersed in a polymeric matrix. Typical hole transport layer materials are disclosed, for example, in U.S. Patent No. 4,265,990 to M. Stolka et al., and U.S. Patent No. 4,346,158 to Pai et al.
