A photoconductive sleeved primary image-forming member roller for use in an electrophotographic machine comprising a central member including a rigid cylindrical core member and a compliant layer formed on the core member; and a flexible, replaceable, removable, photoconductive sleeve member in the form of an endless tubular belt that surrounds and nonadhesively intimately contacts the central member.

Sleeved Photoconductive member and method of making

A photoconductive sleeved primary image-forming member roller for use in an electrophotographic machine comprising a central member including a rigid cylindrical core member and a compliant layer formed on the core member; and a flexible replaceable removable photoconductive sleeve member in the form of an endless tubular belt that surrounds and non-adhesively intimately contacts the central member.

Sleeved photoconductive member and method of making

An intermediate transfer roller that functions as an image receiving member within a reproduction apparatus having a rigid cylindrical core member and at least one layer of an elastically deformable structure surrounding the core member, the elastically deformable structure preferably has an effective Poisson's ratio in the range of 0.2 to 0.4.

Method and apparatus for an intermediate image transfer member

A drum assembly comprises a replaceable sleeve of resilient material supported by a rigid cylindrical mandrel having an air bearing at one end to facilitate loading and removal of the resilient sleeve. The air bearing is provided by a pair of cooperating plates one of which is scored with equally spaced and radially extending slots. When urged together, the plates define a central air chamber and a plurality of radially-extending passages serving to direct pressurized air radially from one end of the mandrel.

Image transfer drum for document printer/copier

In accordance with the invention, there is provided a reproduction method including forming a toner image on a moving primary image-forming member (PIFM) which is a first double-sleeved roller including a rigid cylindrical core member, a replaceable removable compliant inner sleeve member (ISM) in nonadhesive intimate contact with and surrounding the core member, and a replaceable removable photoconductive outer sleeve member (OSM) in nonadhesive intimate contact with and surrounding the ISM; electrostatically transferring the toner image, from the PIFM to a counter-rotating intermediate transfer member (ITM) which is a second double-sleeved roller, in a first transfer nip width produced by a pressure contact between the PIFM and the ITM, an electric field urging the toner image from the PIFM to the ITM, wherein the ITM includes a rigid cylindrical core member, a compliant ISM in nonadhesive intimate contact with and surrounding the core member, and a compliant resistive OSM in nonadhesive intimate contact with and surrounding the ISM.
