A method for developing toner for use in a single component development system, wherein the process includes a) contacting a styrene acrylate polymer binder resin having a weight average molecular weight (Mw) of from about 50 to about 100 Kpse, and a number average molecular weight (Mn) of from about 10 to about 30 Kpse, a wax selected from the group consisting of polypropylene and polyethylene, and at least one colorant to produce a toner blend, b) aggregating the blend by heating at a temperature at or above the glass transition temperature of the styrene acrylate resin to form an aggregated toner core; c) adding a second binder resin to the aggregated toner core to form a shell over said toner core thereby forming a core-shell toner; d) growing said core-shell toner to a desired size; e) coalescing the core-shell toner by heating at a temperature above the glass transition temperature of the second latex; and f) recovering toner particles, wherein the toner particles have an onset glass transition temperature of from about 50.degree. C. to about 60.degree. C., and a circularity of from about 0.950 to about 0.990.
