Abstract

A method for manufacturing toner includes combining a polymer resin and an organic solvent to obtain an oil-based solvent; combining a dispersion stabilizer with water to obtain a water-based solvent; adding an amphiphilic solvent to the water-based solvent; emulsifying the oil-based solvent in the water-based solvent to form emulsion particles; and removing the organic solvent from the emulsion particles.
