Patent ID: 7001653

Claim:
A fusing-station roller for use in a fusing station of an electrostatographic machine, said fusing-station roller elastically deformable, said fusing-station roller comprising: a core member, said core member rigid and having a cylindrical outer surface; a resilient layer, said resilient layer formed on said core member; wherein said resilient layer is a fluoropolymer material, said fluoropolymer material made from an uncured formulation by a curing; wherein said uncured formulation includes a fluoro-thermoplastic polymer, said fluoro-thermoplastic polymer comprising a copolymer, said copolymer made of monomers of vinylidene fluoride (CH 2 CF 2 ), hexafluoropropylene (CF 2 CF(CF 3 )), and tetrafluoroethylene (CF 2 CF 2 ), said copolymer having a composition of: —(CH 2 CF 2 )x—, —(CF 2 CF(CF 3 ))y—, and —(CF 2 CF 2 )z—, wherein, x is from 1 to 50 mole percent, y is from 9 to 59 mole percent, z is from 40 to 90 mole percent, x+y+z equals 100 mole percent; wherein said uncured formulation includes microsphere particles, said microsphere particles having flexible walls; wherein said microsphere particles have a predetermined weight percentage in said uncured formulation; and wherein in addition to said microsphere particles, said uncured formulation includes solid filler particles.
