ABSTRACT:
An electrophotographic imaging member is described comprising a substrate, a layer comprising an amorphous hole injecting material selected from the group consisting of halogen doped selenium, gold, silver, platinum and carbon black, the halogen doped selenium consisting essentially of selenium and between about 200 parts per million and about 2,000 parts per million by weight halogen, and at least one thermal hole generating selenium alloy photoconductive layer. This electrophotographic imaging member may contain other layers such as a hole transport layer, a layer between the hole transport layer and thermal hole generating selenium alloy photoconductive layer, and a thin protective overcoating layer suitable for Carlson type imaging processes. An electrophotographic imaging process employing this electrophotographic imaging member is also described.
