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 100 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.
A fuser member comprising a substrate, and thereover, an intermediate layer comprising silicone rubber, and an outer layer positioned on said intermediate layer, wherein said outer layer comprises perfluoroalkoxy polytetrafluoroethylene and carbon black filler, wherein said outer layer has a resistivity, tailored according to a size and particle geometry of the carbon black therein, to be from about 1×10−4 to about 1×10−8 ohms/square.
An image forming apparatus for forming images on a recording medium comprising a charge-retentive surface to receive an electrostatic latent image thereon;
- a development component to apply toner to the charge-retentive surface to develop an electrostatic latent image to form a developed image on the charge retentive surface;
- a transfer film component to transfer the developed image from the charge retentive surface to a copy substrate;
- and a fuser member and fuser member for fusing toner images to a surface of the copy substrate, wherein said fuser member comprises a substrate, and thereover, an outer layer comprising perfluoroalkoxy polytetrafluoroethylene and carbon black filler wherein said outer layer has a resistivity, tailored according to a size and particle geometry of the carbon black filler therein, to be from about 1×10−4 to about 1×10−8 ohms/square, and wherein said 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.
