摘要:
A roller for use as a fusing roller or a pressure roller or a drying roller in a system for treating printed ink image-bearing substrates and a composition for coating the outside of the roller. The composition is a reaction product of a high molecular weight, reactive cross-linkable poly(dialkylsiloxane), a cross-linked poly(dialkylsiloxane) including a filler and a silane cross-linking agent.
摘要:
A roller composition for forming an outer coating on the roller. The composition includes an addition cure polysiloxane component and a high molecular weight reactive polyfunctional poly(alkylsiloxane) component. The coated roller is effective for drying and fusing ink images on a substrate.

A fuser belt comprising in order a substrate comprising a polyimide substrate, an epoxy primer layer comprising an epoxy resin having the following structure: where R1 and R2 are each independently H or an alkyl group containing 1 to about 4 carbon atoms, and R3 and R4 are each independently H, F, or an alkyl group containing 1 to about 4 carbon atoms, Z is a carbonyl cross-linking group, and x is an integer from 1 to about 10 and said epoxy priming layer also comprising an anhydride crosslinking agent cyclic mono anhydride or dianhydride having the following structure: and mixture thereof where R is an alkyl group containing 6 to about 8 carbon atoms and a toner release layer comprising a silsesquioxane.
摘要:
A toner fuser member contains a substrate on which is disposed a toner release surface layer formed from a composition that includes a silsesquioxane and a curable epoxy resin. On curing, the composition forms an interpenetrating polymer network of the silsesquioxane and cured epoxy resin.
摘要:
Method and apparatus for validating that a fuser member presumptively belongs to a class of fuser member for imparting a certain surface finish to an electrophotographic output print, and/or validating that the fuser member has a heating behavior within specification. Utilizing a temperature-sensing device for measuring temperature of the fuser member during heating thereof, a validation number is computed for comparison with a range of validation numbers associated with the class. If the validation number is included in the range, membership in the class is confirmed and/or the fuser member is shown to be within specification. Additionally, an auxiliary measuring device can be associated with the fuser roller to generate signals for computing, from measurements of a temperature-dependent property of the roller, a validation number relating to the temperature-dependent property.

摘要:
An oil-free process for forming a fused toner image on a receiver includes forming on a receiver, an image including toner particles that contain a non-crosslinked linear polymeric binder, a wax, and a colorant; and contacting the receiver bearing the toner particle image with a fuser member containing a support, a cushion layer overlying the support, and a release layer overlying the cushion layer. The release layer includes a cured fluorocarbon thermoplastic random copolymer, a cured aminosiloxane copolymer, and a zinc oxide particulate filler. The cured fluorocarbon thermoplastics random copolymer contains —(CH2CF2)x—, —(CF2CF(CF3)y—, and —(CF2CF2)z— subunits, wherein x is from 1 to 40 or 60 to 80 mole percent, y is from 10 to 90 mole percent, z is from 10 to 90 mole percent, and x+y+z equals 100 mole percent. The receiver in contact with the fuser member is subjected to conditions effective in the absence of a release oil for fixing the toner particle image to the receiver.
