A process for preparing a toner for electrostatic image development, the process comprising the steps of: (S1) mixing an aqueous pigment dispersion with an aqueous resin particle dispersion containing two or more kinds of self-dispersible polyester resin particles as binder resins to prepare a mixture; and (S2) adding a polyvalent metal salt as a flocculant to the mixture while stirring to form aggregates having the pigment bonded to the resin particles, wherein the self-dispersible polyester resins each are prepared by reacting a carboxylic acid compound with an alcohol compound inclusive of a polyhydric alcohol, and the carboxylic acid compound includes one or more kinds of a polycarboxylic acid having three or more carboxyl groups and its acid anhydride, the self-dispersible polyester resin particles are made from two or more kinds of self-dispersible polyesters having different glass transition temperatures, of which the lowest glass transition temperature is not lower than 40.degree.
