Claims19
A transfer assist member comprising a plurality of layers, one of said layers being a check film layer comprised of a thermoplastic layer on a polymer layer and wherein said polymer layer is comprised of a polyethylene terephthalate or a polyethylene naphthalate.
A composite toner transfer assist blade comprising a plurality of bonded layers, and a bonded check film layer comprised of a partially conductive thermoplastic layer contained on a polymer layer substrate of a polyalkylene terephthalate and wherein the top layer of said plurality of layers is a wear resistant layer, wherein said thermoplastic is selected from the group consisting of a polycarbonate, a polyester, a polysulfone, a polyamide, a polyimide, a polyamideimide, a polyetherimide, a polyether ether ketone, a polyaryl ether, a polyphenyl oxide, a polyphenyl sulfide, and mixtures thereof, and said thermoplastic layer further optionally includes conductive components, silicas, plasticizers, fluoropolymer particles of tetrafluoroethylene polymers, trifluorochloroethylene polymers, hexafluoropropylene polymers, vinyl fluoride polymers, vinylidene fluoride polymers, difluorodichloroethylene polymers or copolymers, polysiloxane polymers, and mixtures thereof.
A xerographic process for providing substantially uniform contact between a copy substrate and a toner developed image located on an imaging member comprising a toner transfer flexible assist blade that comprises a plurality of adhesive bonded layers, wherein said flexible transfer assist blade is adapted to move from a non-operative position spaced from the imaging member to an operative position in contact with the copy substrate on the imaging member, applying pressure against the copy substrate in a direction toward the imaging member, and wherein said plurality of layers comprise a wear resistant layer, and a check film layer comprised of a thermoplastic layer present on a polymer substrate of a polyalkylene terephthalate, a polyester, or mixtures thereof, wherein said thermoplastic is selected from the group consisting of a polycarbonate, a polyester, a polysulfone, a polyamide, a polyimide, a polyamideimide, a polyetherimide, a polyaryl ether, a polyether ether ketone, a polyphenyl sulfide and mixtures thereof and said thermoplastic layer further includes at least one of a conductive filler, silica, a plasticizer, a fluoropolymer, a polysiloxane and mixtures thereof and wherein said plurality of layers are comprised of three polyester layers situated between said check film and said wear resistant layer, wherein said thermoplastic is a polycarbonate, a polyester, and mixtures thereof, and wherein said wear resistant layer is comprised of a polyethylene as represented by the following formulas/structures
- wherein n represents the number of repeating segments from about 100,000 to about 300,000, and wherein from about 95 to about 100 percent of the toner developed image is transferred to said copy substrate comprised of paper, and wherein said thermoplastic overcoat layer has a resistivity of from about 1×107 to about 10×109 ohm as measured by a Resistance Meter.
