Processes for preparing ionographic imaging member including providing a flexible, shrinkable tube containing a dielectric film forming polymer having a Tg of at least about -40°C., charge decay of less than about 2 nonocoulombs per cm2 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.
