Processes for preparing ionographic imaging member including providing a flexible, shrinkable tube containing a dielectric film forming polymer having a T.sub.g of at least about -40.degree. C., charge decay of less than about 2 nonocoulombs per cm.sup.2 per second and elastic memory, providing a cylindrical support member having an outer diameter that is less than the inner diameter of the flexible tube, applying a continuous coating on the interior of the tube or on the exterior of the cylindrical support member, the coating comprising a material selected from the group consisting of an electrically conductive material, an adhesive material and mixture thereof, shrinking the tube to bring the inner surface of the tube and the outer surface of the cylindrical support member into intimate physical contact with the continuous coating. This imaging member may be employed in an ionographic imaging process.
An ionographic imaging process comprising providing an ionographic imaging member comprising a cylindrical support member bearing a shrunken continuous flexible tube around the periphery of said support member, said tube comprising a dielectric thermoplastic film forming polymer having a T.sub.g of at least about -40.degree. C. and charge decay of less than about 2 nanocoulombs per cm.sup.2 per second, said tube having a substantially uniform thickness and an outer imaging surface and an inner surface substantially parallel to each other, the interface between said inner surface of said tube and said periphery of said support member comprising electrically conductive material;
A process for preparing an ionographic imaging member comprising providing a flexible, shrinkable tube comprising a dielectric film forming polymer having a Tg of at least about -40.degree. C., charge decay of less than about 2 nanocoulombs per cm.sup.2 per second and elastic memory, said tube having a substantially uniform thickness and an outer surface and an inner surface substantially parallel to each other, providing a cylindrical support member having an outer diameter that is less than the inner diameter of said flexible tube, applying a continuous coating on said inner surface of said tube or on the outer surface of said cylindrical support member, said coating comprising a material selected from the group consisting of an electrically conductive material, an adhesive material and mixture thereof, shrinking said tube to reduce said inner diameter of said flexible tube to bring said inner surface of said tube and said outer surface of cylindrical support member into intimate physical contact with said continuous coating.
