A composite toner transfer assist blade comprising a plurality of bonded layers inclusive of a bonded check film layer comprised of a crosslinked layer mixture of epoxy resins and carboxylated polyesters contained on a polymer layer substrate of a polyalkylene terephthalate, a polyester, or mixtures thereof, wherein said epoxy resin is a bisphenol A glycidyl ether derived from the reaction of epichlorohydrin and bisphenol A, and said carboxylated polyester is comprised of reaction products of diethylene glycol, neopentyl glycol, terephthalic acid and trimellitic acid, and further including conductive components, catalysts, optional silicas, leveling agents, optional plasticizers, and optional fluoropolymer particles of tetrafluoroethylene polymers, trifluorochloroethylene polymers, hexafluoropropylene polymers, vinyl fluoride polymers, vinylidene fluoride polymers, difluorodichloroethylene polymers, 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 providing said contact by using 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 comprises at least one of a check film layer comprised of a crosslinked mixture of epoxy resins and carboxylated polyesters present on a polymer substrate of a polyalkylene terephthalate, a polyester, or mixtures thereof, and said crosslinked epoxy resins and carboxylated polyesters mixture layer further includes at least one of a conductive component, a silica, a plasticizer, a catalyst of an amine, a phosphonium, a zinc complex or mixtures thereof, a fluoropolymer, a leveling agent and mixtures thereof, and optionally curing said mixture thereby resulting in a crosslinking value of from about 75 to about 100 percent.
