Oil-free process for full color digital printing
First Claim
1. A release-oil free process for forming a fused toner image including:
- forming an image including toner particles on a receiver, said toner particles including a non-crosslinked linear polymeric binder, a wax, and a colorant;
contacting said receiver bearing said image including toner particles with a fuser member including a support, a cushion layer overlying said support, and a release layer overlying said cushion layer, said release layer including a cured fluorocarbon thermoplastic random copolymer, a cured aminosiloxane copolymer, and a particulate filler including zinc oxide, and said cured fluorocarbon thermoplastic random copolymer 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 90 mole percent, z is from 10 to 90 mole percent, and x+y+z equals 100 mole percent; and
subjecting said receiver in contact with said fuser member to conditions effective in the absence of a release oil for fixing said image comprising toner particles to said receiver, thereby forming a fused toner image on said receiver.

Abstract
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.
