Abstract
A selenium photoconductor has a charge transport layer and a charge generation layer formed on a conductive substrate. Both the charge generation layer and the charge transport layer are made from a selenium-arsenic alloy, with the charge generation layer having a concentration of arsenic greater than the concentration of arsenic in the charge transport layer. This concentration distribution results in a photoconductor having excellent charge-generation efficiency and mobility. In an alternate embodiment, a halogen is doped into the charge generation layer and charge transport layer. The resulting photoconductor is useful in large-scale, high speed printing operations.
