US Patent 7510814 Toner and methods of producing same

A toner and a method of producing same. In one embodiment, the method includes the steps of forming an organic phase containing a resin, an organic solvent, a colorant, a charge control agent, and a phase change stabilizer, wherein the organic solvent is characterized in that the resin is soluble in the organic solvent and the organic solvent and water are at least partially miscible; forming an aqueous phase containing water, an anticoagulant, an accelerant, and optionally an auxiliary agent; mixing the aqueous phase with the organic phase to form a solution having resin colloidal microparticles formed and stably dispersed therein, whereby the resin colloidal microparticles aggregate, coalesce and solidify out into resin particles in the solution, meanwhile the organic solvent is removed from the resin particles by the aqueous phase; and curing the resin particles to obtain toner particles having shapes, diameters, and diameter distribution that are controllable.
