Abstract
An electrophotographic imaging member comprising a substrate, a ground plane layer comprising a titanium metal layer contiguous to the substrate, a charge blocking layer contiguous to the titanium layer, a charge generating binder layer and a charge transport layer. This photoreceptor may be prepared by providing a substrate in a vacuum zone, sputtering a layer of titanium metal on the substrate in the absence of oxygen to deposit a titanium metal layer, applying a charge blocking layer, applying a charge generating binder layer and applying a charge charge transport layer. If desired, an adhesive layer may be interposed between the charge blocking layer and the photoconductive insulating layer.

A process for the preparation of an electrophotographic imaging number comprising providing a substrate in a vacuum zone, sputtering titanium on said substrate in the absence of oxygen to deposit a titanium metal layer, applying a blocking layer comprising a siloxane, said siloxane comprising a reaction product of a hydrolyzed silane having the structural formula ##STR6## wherein R.sub.1 is an alkylidene group containing 1 to 20 carbon atoms and R.sub.2 and R.sub.3 are independently selected from the group consisting of H, a lower alkyl group containing 1 to 3 carbon atoms, a phenyl group, a poly(ethylene)amino group and an ethylene diamine group, applying a charge generating binder layer and applying a charge transport layer comprising a resin binder and a diamine compound.
An electrophotographic imaging member comprising a photoconductive member comprising a substrate, a titanium metal layer contiguous to said substrate, a blocking layer comprising a siloxane, said siloxane comprising a reaction product of a hydrolyzed silane having the structural formula ##STR8## wherein R.sub.1 is an alkylidene group containing 1 to 20 carbon atoms and R.sub.2 and R.sub.3 are independently selected from the group consisting of H, a lower alkyl group containing 1 to 3 carbon atoms, a phenyl group, a poly(ethylene)amino group and an ethylene diamine group, a charge generating binder layer and a charge transport layer comprising a resin binder and a diamine compound.
An electrophotographic imaging member comprising a substrate, a titanium metal layer contiguous to said substrate, a blocking layer comprising a siloxane, said siloxane comprising a reaction product of a hydrolyzed silane having the structural formula ##STR10## wherein R.sub.1 is an alkylidene group containing 1 to 20 carbon atoms and R.sub.2 and R.sub.3 are independently selected from the group consisting of H, a lower alkyl group containing 1 to 3 carbon atoms, a phenyl group, a poly(ethylene)amino group and an ethylene diamine group, an adhesive layer comprising a film forming polymer, a charge generating binder layer comprising particles of amorphous selenium, trigonal selenium, and selenium alloys selected from the group consisting of selenium-telurium, selenium-telurium-arsenic and mixtures thereof dispersed in a binder of polyvinyl carbazole, and a layer comprising a solid solution of a polycarbonate resin mterial and a diamine compound, said diamine compound of one or more compounds having the general formula:
- ##STR11## wherein X is selected from the group consisting of an alkyl group having from 1 to about 4 carbon atoms and chlorine.
