PROBLEM TO BE SOLVED: To provide a method for producing resin particles having excellent low-temperature meltability and heat-resistant storage stability and uniform particle diameter. SOLUTION: The method for producing the resin particles comprises mixing of an aqueous dispersion (W) of resin particles (A) containing a crystalline resin (a) having a crystallinity of 10-95%, a melting point of 50-150°C and a number-average molecular weight of 500-1,000,000 with a resin (b) or its organic solvent solution or a precursor (b0) of the resin (b) or its organic solvent solution (O) to disperse the component (O) in the dispersion (W), reacting the precursor (b0) in the case of using the (b0) or its organic solvent solution, to form resin particles (B) containing (b) in the aqueous dispersion (W) of (A) and prepare an aqueous dispersion (X) of resin particles (C) containing the resin particles (A) attached to the surface of the resin particle (B) and removing of the aqueous medium from the dispersion (X).
