  • Patent number: 5714288
    Abstract: A particle toner image is formed on a primary image member (21), such as a photoconductor; electrostatically transferred to an intermediate transfer member (42); and then electrostatically transferred to a receiving sheet. The intermediate transfer member (42) includes a substrate, a compliant blanket (19), and a thin, hard overcoat (80) sectioned into small, discreet segments (81), said segments being separated cracks (85) having a width less than 20 .mu.
    Type: Grant

  • Patent number: 5595823
    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: ##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 aluminum 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 aluminum oxide has a concentration of from 20 to 40 percent of the total volume of the layer.

  • Patent number: 5536352
    Abstract: This invention provides the method of centrifugal casting consisting of the steps of: adding a polymeric material to a centrifugal apparatus; centrifuging said polymeric material until said polymeric material is cast; removing said cast polymeric material from said centrifugal apparatus; and mounting said cast polymeric material to an outside surface of a support, whereby the air interface side of said cast polymeric material is furthest from the outside surface of the support.

  • Patent number: 5464698
    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:--(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.
