摘要： An improved donor member for applying a toner release agent to a toned 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:

        ―(CH 2 CF 2 )x―, ―(CF 2 CF(CF 3 )y―, and ―(CF 2 CF 2 )z―,

and 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. A fuser apparatus for electrostatographic printing comprises a fuser roll and a pressure roll forming a nip, a supply of offset preventing oil contained in a reservoir, and a donor roll for delivering the offset preventing oil to a receiver bearing a toner image, wherein the donor roll has an outermost layer formed from the described cured composition comprising a fluorocarbon thermoplastic random copolymer, a curing agent, particulate zinc oxide, and a curable aminosiloxane.

摘要： A controlled-modulus fusing-station member (20) inclusive of a durable, tough, elastically deformable layer (24) incorporating hollow flexible filler particles (28). The elastically deformable layer (24) can be a single layer on a substrate (26), the substrate preferably a core member of a fuser roller or a pressure roller. Alternatively, a protective or gloss control fluoropolymer layer (22) is formed on the elastically deformable layer (24). The elastically deformable layer (24) is made from a dry formulation inclusive of: a fluoroelastomer powder; microspheres in the form of unexpanded microspheres or expanded microballoons; and solid filler particles including strength-enhancing filler particles and thermal-conductivity-enhancing filler particles. The dry formulation is thermally cured or electron-beam cured.
