Abstract: A method for producing a substrate for a photoconductive drum includes etching the substrate with a self-limiting acid that removes the metal oxides from but does not affect the surface roughness of the substrate inner and outer surface.

Abstract: A photoconductive member for use in an electrophotographic machine includes a substrate having an inside and outside surface. An inner smoothing layer is disposed over the inside surface of the substrate thereby improving the compatibility of the photoconductive member with an air-mounting process by which the photoconductive member is operably associated with a mandrel.

Abstract: A fixture for a double-sleeved roller for assisting replacement of an inner sleeve member (ISM) thereon. The fixture attaches to a fixture-accepting configuration (FAC) including an end plate (EP), which FAC includes passageways for conveying jets of pressurized air to the ISM. The fixture includes a low-surface-energy-coated tubular member (TM) and a mating member (MM) cooperatively forming passageways for creating radially-directed air jets at the perimeter of the MM. The MM and EP cooperatively form another set of passageways for similarly creating air jets. The EP, MM, and TM each includes a cylindrical portion with adjoining tapered portion, the respective tapered portions mutually defined by a conical envelope. The tapered portion of the TM tapers into a cylindrical length merging into a narrowing portion. In all, the air jets are formed from a common source of pressurized air.

Abstract: A double-sleeved roller (DSR) including: a mandrel having a disconnectable end incorporating three termination plates having specified axial profiles; a replaceable inner sleeve member (ISM) mounted on the mandrel; and, a replaceable multilayer outer sleeve member (OSM) including at least one synthetic layer with the OSM surrounding the ISM. The mandrel, adapted to support a non-reinforced ISM, includes the termination plates joined together so as to define two sets of channels for selectively conveying pressurized air to either OSM or ISM for radial expansion thereof. The termination plates have specialized outer shapes, with each termination end plate including a cylindrical portion adjoining a tapered portion. For removal and/or replacement of the OSM or the ISM, a removable support member is moved away from the disconnectable end of the roller while the other end of the roller continues to be supported in cantilever fashion.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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 wi
