A method for producing a resin particle dispersion includes: obtaining a phase-inverted emulsion by adding a neutralizer to a resin solution prepared by dissolving a resin having an acid value in an organic solvent to thereby neutralize the resin and then adding an aqueous medium to the resulting resin solution to subject the resin to phase inversion emulsification; and removing the organic solvent from the phase-inverted emulsion. In the course of obtaining the phase-inverted emulsion, a maximum agitation power per unit mass (kg) of the resin when the resin solution containing the aqueous medium added thereto is agitated to perform the phase inversion emulsification is from 0.4 W to 20 W inclusive.
