Patent ID: 7008678

Claim:
For use in a fusing station of an electrostatographic machine, an elastically deformable fusing-station roller, said fusing-station roller comprising: a core member, said core member being substantially rigid and having a cylindrical outer surface; a base cushion layer, said base cushion layer formed on said core member; a protective layer coated on said base cushion layer; wherein said base cushion layer is a thermally cured polyorganosiloxane material made by an addition-polymerization of an uncured formulation, said uncured formulation including hollow filler particles in form of microballoons having flexible walls, said microballoons having a predetermined hollow-filler concentration in said uncured formulation, and said uncured formulation further including solid filler particles; wherein the thermal conductivity of said base cushion layer is in a range of approximately between 0.2 BTU/hr/ft/° F.–0.7 BTU/hr/ft/° F.; and wherein said addition-polymerization of said uncured formulation is carried out at a temperature below 100° C.
