Abstract:
1. A process for producing an electrostatic image developing toner, the process comprising: (a) polycondensing at least one member selected from the group consisting of polycondensable monomers, oligomers of the polycondensable monomers, and prepolymers of the polycondensable monomers in the presence of a compound having a solubility parameter of 8 or less and at a temperature of from about 70° C. to 130° C.; (b) emulsifying the polycondensed product in an aqueous medium to obtain a resin particle liquid dispersion; (c) aggregating resin particles in a liquid dispersion comprising the resin particle liquid dispersion to obtain aggregate particles; and (d) heating and coalescing the aggregate particles to obtain an electrostatic image developing toner.
