Abstract: An electrically conductive brush is provided for effecting simultaneous charging and cleaning of a photoreceptor surface. The brush is constructed of alternate conductive and non-conductive segments which causes one conductive segment which is being used for charging to be electrically isolated from another conductive segment which is being used for cleaning. Thus, different voltages can be simultaneously applied to each of the segments without adversely affecting the operation of the other. A single detoning roller is also provided for removing toner particles from the brush, the detoning roller being positioned adjacent the cleaning segment to allow for the application thereto of a lower voltage than would be required if the detoning roller was used in conjunction with a charging brush of the prior art or with the charging segment of the brush of this invention.

Abstract: A fuser member and method of fusing or fixing thermoplastic resin powder images to a substrate in a fuser assembly of the type wherein a polymeric release agent having functional groups is applied to the surface of the fuser member is disclosed. The fuser member comprises a base member having an elastomer surface with metal-containing filler therein. Metal containing fillers include metals, metal alloys, metal oxides and metal salts. Exemplary of such a fuser member is an aluminum base member coated with poly(vinylidene fluoride-hexafluoropropylene) copolymer having lead oxide filler dispersed therein and utilizing mercapto-functional polyorganosiloxane as a release agent.

Abstract: Corona discharge electrodes are coated with compressed dielectric materials. A corona discharge electrode is placed under tension and coated with a molten, viscous dielectric material, such as glass, while under tension. The dielectric material is allowed to cool so that the dielectric material becomes bonded securely to the corona discharge electrode. The tension upon the corona discharge electrode is released thereby causing a compression of the dielectric material adhered thereto. The resulting dielectric coated corona discharge electrode has a substantially improved life and delivers substantially uniform currents.

Abstract: Polymeric release agents having functional groups such as carboxy, hydroxy, epoxy, amino, isocyanate, thioether or mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having excellent toner release properties for conventional electroscopic thermoplastic resin toners. The functional polymeric fluids interact with the fuser member in such a manner as to form a thin, thermally stable interfacial barrier at the surface of the fuser member while leaving an outer film or layer of unreacted release fluid. The interfacial barrier is strongly attached to the fuser member surface and prevents electroscopic thermoplastic resin toner material from contacting the outer surface of the fuser member. The material on the surface of the fuser member is of minimal thickness and thereby represents a minimal thermal barrier.

Abstract: Polyorgano siloxanes having functional mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having superior toner release properties for electroscopic thermoplastic resin toners. The polyorgano siloxane fluids having functional mercapto groups interact with the fuser member in such a manner as to form an interfacial barrier at the surface of the fuser member while leaving an unreacted, low surface energy release fluid as an outer layer or film. The interfacial barrier is strongly attached to the fuser member surface and prevents toner material from contacting the outer surface of the fuser member. The material on the surface of the fuser member is of minimal thickness and thereby represents a minimal thermal barrier.

Abstract: Rolls, belts and other biasable members having controlled resistivity are described. The resistivity of the elastomeric resilient polyurethane coating on biasable members is controlled by ionic additives incorporated in the polyurethane. Biasable members having at least one layer or coating of a hydrophilic elastomeric polyurethane containing resistivity altering compounds or agents have substantially reduced resistivity changes with changes in relative humidity. The utility of such biasable members is in the transfer of xerographic images from a photoconductor to a final support sheet where the member, for example, a bias transfer roll, electrically cooperates with a photoconductor to establish a directional force field therebetween.
