ABSTRACT:
A toner fuser member has a substrate, on which is formed a toner release surface layer from a composition that includes: about 95 wt. % to about 99.9 wt. % of a cross-linked, glycidyl end-capped bisphenolic polymer having the formulawhere R1and R2are each independently H or an alkyl group containing 1 to about 4 carbon atoms, and R3and R4are each independently H, F, or an alkyl group containing 1 to about 4 carbon atoms, Z is a carbonyl cross-linking group, and x is an integer from 1 to about 10; and about 0.01 wt. % to about 5 wt. % of a perfluoroalkylsubstituted glycidyl-reactive compound having the formulawhere R5is H or F, Q is OH or SiR6R7R8, R6, R7, and R8being independently selected from the group consisting of Cl, OH, an alkyl group containing 1 to about 4 carbon atoms, an alkoxy group containing 1 to about 4 carbon atoms, an acyloxy group containing 2 to about 4 carbon atoms, and an amino group containing 0 to about 4 carbon atoms; and n is an integer from 1 to about 15. When Q is SiR6R7R8, at least one of R6, R7, and R8is Cl, OH, or an alkoxy, acyloxy, or amino group.
