Abstract
A method of making toner particles, including: mixing, at less than about 17° C. and without homogenizing, a resin emulsion with a coagulant, a colorant, an optional wax, and optional additives, to form pre-aggregated particles in a slurry; heating the slurry to form aggregated toner particles; freezing aggregation of the particles in the slurry once at a desired aggregated particle size; and further heating the aggregated particles in the slurry to coalesce the aggregated particles into toner particles.
