Method of coating fuser member with thermoplastic containing zinc oxide and aminosiloxane

A fuser member comprising a support and coated thereon a fluorocarbon elastomer layer containing: (1) a silicon carbide filler and a cupric oxide filler; and/or (2) a silicon carbide filler treated with a silane coupling agent having a reactive functional group, the fuser member further having a functionalized polydimethylsiloxane release agent applied to the fluorocarbon elastomer layer in an amount sufficient to produce, upon incubation at elevated temperature, a surface having improved toner release properties on said outermost layer.

Fluorocarbon fuser member with silicon carbide filler

A fuser member having an outermost layer comprising a fluoroelastomer with thermally conductive fillers treated with a mercapto-functionalized silane coupling agent that is interactive with a fluoroelastomer to provide a fuser roller surface of decreased toner offset and abrasion and increased toner release and thermal conductivity.

Fuser member with mercapto-treated Al2O3 filler

A fuser member having improved toner offset release and wear characteristics. The outermost layer comprises a fluoroelastomer with thermally conductive fillers which are surface treated with a coupling agent that is interactive with the fluoroelastomer and with a release agent which may, optionally, be used on the surface of the fluoroelastomer layer.

Fuser member with surface treated Al.sub.2 O.sub.3 and functionalized

A fuser member useful for heat-fixing an electrographic toner to a substrate. The fuser member has a core and a layer overlying the core. The layer includes a cured fluorocarbon random copolymer having subunits with the general structures:

Offset preventing oils for treated (IR light) or untreated zirconia ceramic or its composites fuser rollers are disclosed.

Toner offset preventing oils for zirconia ceramic and its composites

A toner fuser member having improved toner release properties comprises a substrate and an outermost layer comprising a cured fluoroelastomer that includes at least about 21 mole percent of hexafluoropropylene (HFP) and at least 10 parts per weight of a metal oxide selected from the group consisting of cupric oxide, plumbous oxide, and mixtures thereof. Applying to the outermost layer of the fuser member an effective amount of a polymethyldisiloxane (PDMS) release agent that, optionally, includes at least one functional group reactive with the fluoroelastomer, followed by incubation at an elevated temperature, produces a surface having enhanced toner release characteristics on the outermost layer. A process for forming a toner fuser member having improved toner release properties comprises forming on a substrate an outermost layer having the above-described composition of cured fluoroelastomer and metal oxide.
