Abstract
An electrophotographic imaging member including PA1 a support substrate layer comprising polyethylene naphthalate substantially free of any oligomers, having a glass transition temperature of between about 100.degree. C. and about 140.degree. C., having a thickness between about 75 micrometers (3 mils) and about 125 micrometers (5 mils) and having a Young's modulus of between about 650,000 and about 1,000,000 pounds per square inch, PA1 an electrically conductive ground plane layer c including titanium, PA1 a hole blocking layer, PA1 an optional adhesive layer, PA1 a charge generation layer including PA2 photoconductive particles dispersed in a film forming binder, and PA1 a hole transport layer, the hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from the charge generation layer and transporting the holes through the hole transport layer.
