Fuser members overcoated with fluorocarbon elastomer containing aluminum oxide
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: 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 aluminum oxide and a material selected from the group consisting of alkaline <INS-S DATE="20020618" ID="INS-S-00001"/>earth <INS-E ID="INS-S-00001"/>metal oxides, alkaline <INS-S DATE="20020618" ID="INS-S-00002"/>earth <INS-E ID="INS-S-00002"/>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 aluminum oxide has a concentration of from 20 to 40 percent of the total volume of the layer.
