Patent ID: 7892160

Claim:
A double-sleeved roller for use in an electrostatographic machine, comprising: a cylindrical rigid core member having an outer diameter; a removable inner sleeve member (ISM) including a compliant layer, the ISM having freestanding (unexpanded) inner and outer diameters, where the freestanding (unexpanded) inner diameter is smaller than the outer diameter of the rigid core, and the ISM being expanded such that the ISM surrounds and intimately contacts said rigid core member; and a removable electrically conductive outer sleeve member (OSM), such that the OSM surrounds and intimately contacts said expanded ISM, wherein the OSM has a freestanding (unexpanded) inner diameter that is larger than the freestanding (unexpanded) outer diameter of the ISM and the OSM has a hoop stiffness that is greater than a hoop stiffness of the ISM, such that the OSM may be slid over the ISM without interference before the ISM is expanded and the ISM and OSM are removable or mountable simultaneously when the ISM is expanded.
