Abstract
A multilayer electrophotographic member (such as a plate or flexible web) of the type for producing an electrostatic latent image thereon has a layer of photoconductive material, such as selenium, overlain by a charge image bearing layer comprising an organic polymeric material having the ability to transport electrical charge carriers therethrough, such as polyvinylcarbazole. The charge image bearing layer also has incorporated therein a plasticizer material selected from the group consisting of phenylether, its oligomers and substituted derivatives of the phenylether moiety.
Claims17
In a multilayer electrophotographic member for producing an electrostatic latent charge image thereon:
- a layer of photoconductive material;
- a layer of organic polymeric material overlying said photoconductive layer and having the ability to transport electrical charge carriers therethrough, said layer of organic polymeric material having incorporated therein a plasticizer material selected from the group consisting of oligomers of phenylether, and derivatives of phenylether with at least one aryl substituent attached to the aromatic nuclei, the plasticizer being present in a concentration within the range of 1 to 100 parts of plasticizer per hundred parts of the organic polymeric material by weight.
