ABSTRACT:
A fuser member having a substrate, a layer thereover including a polymer, and, on the polymeric layer, a coating of a release agent having a mixture of (a) an organosiloxane polymer concentrate containing amino-substituted organosiloxane polymers, wherein there are amino functional groups on at least some of the polymer molecules of the concentrate, the concentrate has a degree of functionality of from about 0.3 to about 0.4 mole percent, the concentrate has a viscosity of from about 800 to about 1,300 centistokes; and (b) a nonfunctional organosiloxane polymer diluent, the diluent has a viscosity of from about 100 to about 2,000 centistokes; the mixture has a degree of functionality of from about 0.05 to about 0.3 mole percent, wherein the mixture has a viscosity of from about 550 to about 1,300 centistokes, and wherein the ratio by weight of concentrate to diluent is from about 1:2 to about 1:30, and an image forming apparatus having the fuser member.
