Abstract: A spots cleaning blade for use in a cleaning apparatus in an imaging apparatus for cleaning agglomerate particles from an imaging surface, the spots cleaning blade comprising a polyether urethane and having a high hardness and low coefficient of friction.

Abstract: An endless flexible seamed belt formed by joining two ends of the material from which the belt is fabricated is provided, the belt having at least one overlapping, butting, interlocking joint to form the endless belt, each end of the at least one overlapping butting, joint, contains a pair of interlocking members having a male projection and a female receptacle geometrically oriented so that the female receptacle on the first end receives the male projection on the second end and the male projection on the first end is received by the female receptacle on the second end to form a joint between the first and second ends, at least one receptacle being formed within and having a substantial depth in a portion of the belt material at the belt ends, at least one projection and receptacle pair being sized and shaped to form at least one pair of mutually mating elements in a combination overlapping, butting and interlocking joint to form the endless belt.

Abstract: An endless flexible seamed belt with a mechanically invisible seam and substantially equivalent in performance to a seamless belt is formed by joining two ends of material from which the belt is fabricated each end of which has a plurality of mutually mating elements in a puzzle cut pattern which are in interlocking relationship in at least one plane and which when joined mechanically enable the flexible belt to essentially function as an endless belt having a substantially uniform thickness.

Abstract: A process for the preparation of a fuser member which comprises applying to a fuser supporting substrate a coating mixture of a fluoropolymer, and an aliphatic alcohol.

Abstract: A sheet registration device including a hub having an axis of rotation and a plurality of resilient plastic blades arranged in radial planes passing through said axis and extending in the direction of said axis beyond one end of the hub towards sheet-engaging tips lying in a common plane normal to said axis said blade being made of a polyurethane elastomer obtained by the reaction of a polytetramethylene ether glycol having the formula HO[(CH.sub.2).sub.4 O].sub.n H where n is from 8 to 41, preferably 39 to 41, and from about 20 to about 95 parts preferably 22 to 26 parts by weight per 100 parts by weight of said glycol of a diisocyanate selected from the group consisting of diphenylmethane diisocyanates, toluene diisocyanates, naphthalene diisocyanates and blends thereof and a sufficient amount of cross linking agents to provide a crosslinked elastomer, said cross linking agents comprising a mixture of from about 75% to 60% by weight of a diol having the formula: HO(R.sub.1) OH where R.sub.

Abstract: A multilayered fuser member for fusing thermoplastic resin toner images to a substrate in a fuser system of the type wherein a polymeric release agent having functional groups is applied to the surface of the fuser member, the fuser member has a base support member, a thermally conductive silicone elastomer layer, an amino silane primer layer, an adhesive layer and an elastomer fusing surface comprising poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) a metal oxide present in the fusing surface to interact with the polymeric release agent to provide an interfacial barrier layer between the fusing surface and the toner and substantially unreactive with the elastomer, the elastomer having been cured from a solvent solution with a nucleophilic curing agent soluble in the solution and in the presence of 4 parts by weight of inorganic base per 100 parts of polymer, the adhesive layer having been cured from a solvent solution of the above composition from which the fusing surface is cured and from a

Abstract: A fuser member and fuser system of a type wherein a polymeric release agent having functional groups supplied to the surface of the fuser member has an elastomer fusing surface comprising poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) wherein the vinylidenefluoride is present in the amount less than 40 mole percent, a metal oxide is present in amounts sufficient to interact with the polymer release agent having functional groups to provide an interfacial barrier layer between the fusing surface and the toner and being substantially unreactive with the elastomer and wherein the elastomer is cured from a solvent solution thereof with a nucleophilic curing agent soluble in the solution and in the presence of less than 4 parts by weight of inorganic base per 100 parts by weight of polymer with the inorganic base being effective to at least partially dehydrofluorinate the vinylidenefluoride.
