An electrostatographic imaging member assembly including a hollow cylindrical electrostatographic imaging member, the member including a substrate, an exterior imaging surface, an interior back surface, a first end and a second end, a rigid cylindrical core support member located within the interior of and coaxially aligned with the cylindrical electrostatographic imaging member, the cylindrical core support member extending from at least the first end to the second end of the imaging member and having an outer surface spaced from the interior back surface of the hollow cylindrical photoreceptor and at least one preformed resilient compressible sleeve under compression between the back surface of the imaging member and outer surface of the cylindrical core support, the compression being sufficient to render the electrostatographic imaging member substantially rigid and substantially free from distortion under electrostatographic image cycling conditions. A process for fabricating this imaging member is also disclosed.
An electrostatographic imaging member assembly comprising a hollow cylindrical electrostatographic imaging member, said member comprising a substrate, an exterior imaging surface, an interior back surface, a first end and a second end, a rigid cylindrical core support member located within the interior of and coaxially aligned with said cylindrical electrostatographic imaging member, said cylindrical core support member having a rounded end and extending from at least said first end to said second end of said imaging member and having an outer surface spaced from said interior back surface of said hollow cylindrical photoreceptor, and at least one preformed resilient compressible sleeve under compression between said back surface of said imaging member and outer surface of said cylindrical core support, said compression being sufficient to render said electrostatographic imaging member substantially rigid and substantially free from distortion under electrostatographic image cycling conditions, said sleeve having an inside diameter and said cylindrical core having an outside diameter prior to inserting said cylindrical core support member within said interior of said cylindrical electrostatographic imaging member, and said inside diameter of said sleeve being less than said outside diameter of said cylindrical core.
