Abstract
The invention provides a fuser roll useful for heat-fixing an electrographic toner to a substrate, wherein the roll comprises a core having thereon a base cushion layer comprising a condensation-crosslinked poly(dimethylsiloxane) elastomer and having at least one other layer thereover, characterized in that the base cushion layer has zinc oxide particles dispersed therein in a concentration of from 8 to 40 percent of the total volume of the base cushion layer. The base cushion layer of such a fuser roll has been unexpectedly found to exhibit only minimal weight loss, creep, and changes in hardness, over time, when subjected to conditions of elevated temperature and cyclic stress.
