Patent ID: 7608325

Claim:
A fuser member comprising a substrate, and thereover, an outer layer comprising perfluoroalkoxy polytetrafluoroethylene and a first carbon black filler having a bulk resistivity of from about 10 0 to about 10 −4 ohms-cm, wherein said outer layer has a resistivity, tailored according to a size and particle geometry of carbon black therein, to be from about 1×10 −4 to about 1×10 −8 ohms/square, wherein said perfluoroalkoxy polytetrafluoroethylene is present in the outer layer in an amount of from about 75 to about 95 percent by weight of total solids, and further wherein said first carbon black filler is present in said outer layer in an amount of from about 5 to about 8 percent by weight of total solids.
