Abstract
A toner composition comprised of pigment, an optional charge enhancing additive and a polyesteramide-siloxane resin of the following Formulas I,II or III ##STR1## wherein m, n and o represent the number of monomer segments present; R is independently selected from the group consisting of aryl and alkyl; and R' is independently selected from the group consisting of alkyl, alkylene and oxyalkylene.
