Patent ID: 7459203

Claim:
A fuser member for a toner fusing system, comprising: (a) a base; and (b) a fusing surface layer comprising: (i) a first elastomer, as a continuous phase; and (ii) a second elastomer, as a discontinuous phase, dispersed through the continuous phase in the form of domains; wherein: the second elastomer is wettable by the first elastomer; the modulus of the second elastomer is greater than the modulus of the first elastomer, at the temperature of the fusing process; the swell level of the first elastomer with a toner fusing system release agent is from about 0.2 to about 0.005; the swell level of the second elastomer with the release agent is greater than zero; and the ratio of the second elastomer swell level to the first elastomer swell level with the release agent is from about 0.5:1 to about 0.02:1.
