Patent ID: 7163999

Claim:
A method for preparing non-spherical resin particles, comprising the steps of: applying a shear force to an aqueous dispersion (II) with increased viscosity formed by adding a thickener (V) to an aqueous dispersion (I) containing resin particles (A); and decreasing the viscosity of the aqueous dispersion obtained by the step described above by adding a viscosity decreasing agent (E); and subjecting the aqueous dispersion obtained by the viscosity decreasing step described above to solid-liquid separation to remove the aqueous medium, wherein the viscosity decreasing agent (E) is α-glycanase and/or β-glycanase, and wherein the viscosity of the aqueous dispersion (II) is in the range of 300 to 100,000 mPa·s (at 25° C.) and the viscosity of the aqueous dispersion after subjecting the viscosity decreasing step is 200 mPa·s or less (at 25° C.).
