Patent ID: 7344819

Claim:
A method for manufacturing toner, the method comprising the steps of: a first combining step of combining a polymer resin and an organic solvent to obtain an oil-based solvent; a second combining step of combining a dispersion stabilizer with water to obtain a water-based solvent; an emulsification step of emulsifying the oil-based solvent in the water-based solvent to form emulsion particles; and a solvent removal step of removing the organic solvent from the emulsion particles; wherein the second combining step includes an additive step of adding an amphiphilic solvent to the dispersion stabilizer, the water, or a mixture of the dispersion stabilizer and the water, wherein the amphiphilic solvent is added in an amount of about 0.4 to about 1.8 times greater than a phase point amount of the amphiphilic solvent in a mixture of the organic solvent and water.
