Disclosed is a preparation method of a toner comprising steps of: (a) preparing a dispersion mixture containing colored polymer particles, a charge controlling agent and organic resin fine particles, in an aqueous medium; (b) allowing said charge controlling agent and organic resin fine particles to be adhered on the surface of said colored polymer particles by salting-out; (c) drying said colored polymer particles having thereon said charge controlling agent and organic resin fine particles; and (d) applying mechanical impact to said colored polymer particles to effect a conversion of said organic resin fine particles into a film on the surfaces of said colored polymer particles.
