A process involving the mixing of a latex emulsion containing resin and a surfactant with a colorant dispersion containing a nonionic surfactant, and a polymeric additive and adjusting the resulting mixture pH to less than about 4 by the addition of an acid and thereafter heating at a temperature below about, or equal to about the glass transition temperature (Tg) of the latex resin, subsequently heating at a temperature above about, or about equal to the Tg of the latex resin, cooling to about room temperature, and isolating the toner product.
