Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for classification with good classifying efficiency and precision without necessitating a large device. SOLUTION: The method for classification of resin particles is characterized in that resin particles are dispersed in a polar solvent and left still, only resin particles of relatively large diameters are made to settle down through the use of interaction of the surface of electrically charged resin particles with the polar solvent, and thus the resin particles are classified into relatively large resin particles and relatively small resin particles by separating the resin particles in the solvent into a layer of sediment containing only resin particles of relatively large particle diameters and a supernatant layer containing resin particles of relatively small particle diameters.
