    摘要: An electrophotographic imaging member includinga 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,an electrically conductive ground plane layer c including titanium,a hole blocking layer,an optional adhesive layer,a charge generation layer includingphotoconductive particles dispersed in a film forming binder, anda 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.
