Toner fuser member having a metal oxide filled fluoroelastomer outer layer with improved toner release

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...

More Information
Summary: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.
