Abstract
A pressure member for use in fixing toner to a receiver comprises a support an intermediate layer disposed on the support, and an outermost layer formed from a cured composition comprising a fluorocarbon thermoplastic random copolymer, a curing agent, a particulate filler containing zinc oxide, and a curable aminosiloxane, wherein the fluorocarbon thermoplastic random copolymer has subunits of: —(CH2CF2)x—, —(CF2CF(CF3)y—, and —(CF2CF2)z—, 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.
Claims23
A pressure member for applying a toner release agent to a toned receiver, said donor member comprising:
- a support, an intermediate layer disposed on the support, and an outermost layer formed from a cured composition comprising a fluorocarbon thermoplastic random copolymer, a curing agent, a particulate filler containing zinc oxide, and a curable aminosiloxane, said fluorocarbon thermoplastic random copolymer is a fluoroplastic having subunits of:
- —(CH2CF2)x—, —(CF2CF(CF3))y—, and —(CF2CF2)z—,
- wherein
- x is from 1 to 40 or 60 to 80 mole percent,
- y is from 10 to 89 mole percent,
- z is from 10 to 89 mole percent, and
- x+y+z equals 100 mole percent.
