ABSTRACT:
A process for making toner particles comprising: (a) forming an emulsion comprising a disperse phase including a first aqueous composition and a continuous phase including molten one or more ingredients of a toner composition, wherein there is absent a toner resin solvent in the continuous phase; (b) performing a phase inversion to create a phase inversed emulsion comprising a disperse phase including toner-sized droplets comprising the molten one or more ingredients of the toner composition and a continuous phase including a second aqueous composition; and (c) solidifying the toner-sized droplets to result in toner particles.
