PROBLEM TO BE SOLVED: To provide a method for producing resin particles and toner particles having a stable and small particle diameter and sharp high circularity. A method for producing toner particles in which a resin A having a polymer a, a colorant, a polymer dispersant B, an organic solvent, and a dispersion medium are mixed and the surface is covered with the polymer dispersant B. A step of forming droplets containing A, a colorant, and an organic solvent; and a step of obtaining toner particles by removing the organic solvent contained in the droplets, and the weight average molecular weight (Mw) of the polymer dispersant B ) Is 50,000 or more and 500,000 or less, the polymer dispersant B is a polymer having a partial structure C and a partial structure D, and the partial structure C has a structure represented by the formula (1), The polymer a, the partial structure C, and the partial structure D satisfy the formulas (2) to (4).
