Abstract

Electrophotographic imaging members containing a plurality of electrically active layers are well known. These imaging members may comprise, for example, a supporting metal or polymeric substrate, an optional metal oxide layer, an optional polymeric interface layer, a charge generating layer and a charge transport layer. Generally, selection of the materials €or the charge transport layer depends upon whether the transport layer is intended to be utilized for electron transport or hole transport. For example, in electron transport systems, the charge transport layer may compose trinitrofluoronone or other electron transport material in a polymeric binder. For hole transport systems, the charge transport layer may, for example, comprise diamine hole transport molecules in a polymeric binder.

Electrophotographic imaging members containing a plurality of electrically active layers are well known. These imaging members may comprise, for example, a supporting metal or polymeric substrate, an optional metal oxide layer, an optional polymeric interface layer, a charge generating layer and a charge transport layer. Generally, selection of the materials &euroor the charge transport layer depends upon whether the transport layer is intended to be utilized for electron transport or hole transport. For example, in electron transport systems, the charge transport layer may compose trinitrofluoronone or other electron transport material in a polymeric binder. For hole transport systems, the charge transport layer may, for example, comprise diamine hole transport molecules in a polymeric binder.

An excellent charge generating layer material has been discovered which may be employed with imaging members having either an electron transport layer or a hole transport layer. This charge generating layer material IS cadmium telluride, Cadmium telluride may function as a p-type or n-type material and is sensitive to both visible and infra-red radiation. If desired, this charge generating layer material may be doped with activators selected from G...
