A process for preparing a toner for electrostatic image development, the process comprising the steps of:(S1) mixing an aqueous pigment dispersion and an aqueous resin particle dispersion containing self-dispersible polyester resin particles as a binder resin to prepare a mixture; and(S2) adding a polyvalent metal salt as a flocculant to the mixture while stirring to form aggregates of the pigment bonded to the resin particles,wherein the self-dispersible polyester resin is prepared by reacting a carboxylic acid compound with an alcohol compound inclusive of a polyhydric alcohol, the carboxylic acid compound being one or more of a polycarboxylic acid having three or more carboxyl groups and its anhydride.
