Abstract
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.
Claims18
A fuser member comprising a support and coated thereon an outermost fluoroelastomer layer comprising a metal oxide filler selected from aluminum oxide, cupric oxide, and mixtures thereof, said filler being treated with a mercapto-functionalized silane coupling agent, wherein the fluoroelastomer layer comprises a fluoroelastomer consisting of the following formula:
- where
- x is from 30 to 90 mole percent,
- y is from 10 to 70 mole percent, and
- z is from 0 to 30 mole percent.
