ABSTRACT:
A fuser member component to fuse the transferred developed image to the copy substrate, wherein the fuser member includes a substrate, an outer polymeric layer, and a release agent material coating on the outer polymeric layer, and the release agent material coating includes a T-type amino-functional siloxane release agent material having amino-functional groups, and the T-type amino-functional siloxane release agent material has the following Formula I:wherein A represents —R4—X, wherein R4represents an alkyl group having from about 1 to about 10 carbons, X represents —NH2or —NHR5NH2with R5representing an alkyl group having from about 1 to about 10 carbons; R1and R2are the same or different and each is selected from the group consisting of an alkyl having from about 1 to about 25 carbons, an aryl having from about 4 to about 10 carbons, and an arylalkyl; R3is a substituted diorganosiloxane chain having from about 1 to about 500 siloxane units; b and c are numbers and are the same or different and each satisfy the conditions of 1≦b≦10 and 10≦c≦1,000, d and d′ are numbers and are the same or different and are 1 or 2, and e and e′ are numbers and are the same or different and are 1 or 2 and satisfy the conditions that d+e=3 and d′+e′=3.
