Abstract

A fuser member useful for heat-fixing an electrographic toner to a substrate. The fuser member has a core and a layer overlying the core. That layer includes a cured fluorocarbon random copolymer having subunits with the general structures: EQU --(CH.sub.2 CF.sub.2).sub.x --, --(CF.sub.2 CF.sub.2).sub.z --, and ##STR1## where x is from 30 to 90 mole percent, y is from 10 to 70 mole percent, and z is from 0 to 34 mole percent. The layer incorporates particulate filler. The filler includes tin oxide and a material selected from the group consisting of alkali metal oxides, alkali metal hydroxides, and combinations thereof. The filler has a total concentration in the layer of from about 25 to 50 percent of the total volume of the layer. The tin oxide has a concentration of from 20 to 40 percent of the total volume of the layer.
