Abstract:
1. A method for producing a resin particle liquid dispersion for an electrostatic image developing toner, the method comprising: preparing an emulsified liquid dispersion comprising an aqueous medium and an oil phase comprising at least polycondensable monomers and radical polymerizable monomers, the oil phase being dispersed in the aqueous medium; polycondensing the polycondensable monomers to obtain a polyester resin particle comprising a polycondensable polymer, the polyester resin particle being dispersed in the aqueous medium to have a median diameter of 0.05 to 1.0 μm; polymerizing the radical polymerizable monomers after the polycondensing to obtain the resin particle liquid dispersion; and rapidly cooling the resin particle liquid dispersion to a range between a temperature of −10° C. and a temperature that is 60° C. lower than the polycondensation temperature (Tc) at a rate of 3 to 20° C./min after the polymerizing, wherein
