20090324308OIL LESS FUSING USING NANO/MICRO TEXTURED FUSING SURFACES - Exemplary embodiments provide a fixing member having a textured surface, and methods for making and using the textured fixing member. The fixing member can include a substrate having one or more functional layers formed thereon. The one or more functional layers can include an outermost or top surface having a surface wettability that is hydrophobic and/or oleophobic; ultrahydrophobic and/or ultraoleophobic; or superhydrophobic and/or superoleophobic by forming textured features. Such fixing member can be used as an oil-less fusing member for high speed, high quality electrophotographic printing to ensure and maintain a good toner release from the fused toner image on an image supporting material(e.g., a paper sheet), and further assist paper stripping. In addition, the textured surface can provide an oil-free, such as wax-free, toner design for the oil-less fixing process.12-31-2009
