Claim Text:
1. A fixing member comprising: a substrate; and a support polymer disposed over the substrate, wherein the support polymer comprises a plurality of structural features that are periodically ordered to form a textured surface, the support polymer consisting essentially of one or more materials selected from the group consisting of polyimide, polycarbonate, polyester, polyamide, polyamide-imide and polyketone, wherein the textured surface comprises a fluoro-polymer in a form selected from the group consisting of a shaft, a pillar, a wire, a rod, a needle, a fiber, a thread, a flake and a combination thereof, the fluoro-polymer having an elongated structure having a diameter ranging from about 10 nanometers to about 1 micron and an aspect ratio ranging from about 100 to about 10000, the fluoro-polymer providing a secondary texture on an outer surface of the periodically ordered structural features thereby resulting in a binary phase surface morphology; wherein the binary phase textured surface has a water contact angle of at least 90°; and wherein the fluoro-polymer is either (i) embedded only in the structural features of the support polymer or (ii) dispersed only on a surface of the support polymer to form the textured surface.
