    摘要： The toner fuser roll of the present invention, which is characterized by good thermal conductivity and resistance to degradation by release agents in addition to excellent wear properties, is capable of producing toner fused images with desirably high gloss. In accordance with the invention, the fuser roll comprises a cylindrical core and a base cushion layer comprising a condensation-cured poly(dimethylsiloxane) elastomer formed on the core. A barrier layer that comprises a cured fluorocarbon polymer and includes a particulate filler overlies the cushion layer. Overlying the barrier layer is a highly smooth outer surface layer comprising an addition-cured poly(dimethylsiloxane) elastomer and having a roughness value, Ra, no greater than about 10 microinches. Further in accordance with the invention is a process for forming the just described toner fuser roll. In addition to its capability of producing a highly smooth PDMS outermost layer, the process is environmentally advantageous, employing coating formulations containing volatile organic compounds at levels below those mandated by environmental regulations.
