Abstract
A process for preparing a toner, includes solvent flashing wax and resin together to emulsify the resin and wax to a sub-micro size; mixing the wax and resin emulsion with a colorant, and optionally a coagulant to form a mixture; heating the mixture at a temperature below a glass transition temperature of the resin to aggregate the resin, colorant, and wax, to form aggregated particles; heating the aggregated particles and coalescent agent at a temperature above the glass transition temperature of said resin, to coalesce the aggregated particles to form toner particles, optionally cooling the mixture; and isolating the toner particles.
