an inner barrier layer disposed over said inner smoothing layer.
2. The photoconductive member of claim 1 , wherein said inner smoothing layer is a polymer.
3. The photoconductive member of claim 1 , wherein said substrate is a metal.
4. The photoconductive member of claim 3 , wherein said metal is nickel.
5. The photoconductive member of claim 1 , wherein said inner barrier layer is a layer of nylon.
6. A photoconductive member, for air mounting on a mandrel, for use in an electrophotographic machine, said photoconductive member comprising:
a substrate having an inside and an outside surface;
an outer smoothing layer disposed over said outside surface of said substrate;
an outer barrier layer disposed over said outer smoothing layer;
a charge generating layer disposed over said outer barrier layer;
a charge transport layer disposed over said charge generating layer;
an inner smoothing layer disposed over said inside surface of said substrate to facilitate air mounting of said photoconductive member on the mandrel; and
an inner barrier layer disposed over said inner smoothing layer.
7. The photoconductive member of claim 6 , wherein said inner smoothing layer is a polymer.
8. The photoconductive member of claim 7 , wherein said inner smoothing layer and said outer smoothing layer each is a polymer.
9. The photoconductive member of claim 8 , wherein said inner smoothing layer and said outer smoothing layer are the same polymer.
10. The photoconductive member of claim 6 , wherein said substrate is a metal.
11. The photoconductive member of claim 10 , wherein said metal is nickel.
12. The photoconductive member of claim 6 , wherein said inner barrier layer is nylon.
13. The photoconductive member of claim 6 , wherein said inner barrier and said outer barrier layer are nylon.
14. The photoconductive member of claim 13 , wherein said inner barrier and said outer barrier layer are the same nylon.
15. An image cylinder for an electrophotographic machine, comprising:
a mandrel configured for being operably disposed within the electrophotographic machine, said mandrel having an outer surface; and
a photoconductive member operably associated with said mandrel, said photoconductive member including a substrate having an inside and an outside surface, said inside surface of said substrate surrounding at least a portion of said outer surface of said mandrel, an inner smoothing layer disposed over said inside surface of said substrate to facilitate air mounting of said photoconductive member on said mandrel, and an inner barrier layer disposed over said inner smoothing layer.
16. The image cylinder of claim 15 , wherein said inner smoothing layer is a polymer.
17. The image cylinder of claim 16 , wherein said photoconductive member further had an outer smoothing layer disposed over said outside surface of said substrate, said outer smoothing layer being a polymer.
18. The image cylinder of claim 17 , wherein said inner and outer smoothing layers are the same polymer.
19. The image cylinder of claim 15 , wherein said inner barrier layer is a layer of nylon.
20. The image cylinder of claim 19 , wherein said photoconductive member further includes:
an outer smoothing layer disposed over said outside surface of said substrate; and
an outer baffler layer disposed over said outer smoothing layer.
21. The image cylinder of claim 20 , wherein said inner and outer barrier layers are the same nylon material.
22. A method for improving the compatibility of a photoconductive member with a mandrel for an air-mounting process by which the photoconductive member is mounted on the mandrel, comprising:
forming an inner smoothing layer over an inside surface of the photoconductive member to facilitate air mounting of said photoconductive member on the mandrel; and
forming an inner barrier layer disposed over said inner smoothing layer.
23. The method of claim 22 , wherein said forming step is a dipping process.
24. The method of claim 22 , wherein said inner smoothing layer is a polymer.
25. The method of claim 22 , wherein said forming step includes simultaneously forming at least part of an outer smoothing layer on an outside surface of the photoconductive member.
26. The method of claim 22 , wherein said further process of forming is a dipping process.
27. The method of claim 22 wherein said inner barrier layer is a layer of nylon.
28. The method of claim 22 wherein the further process of forming includes simultaneously forming an outer barrier layer over said outer smoothing layer.
