To stably produce a toner having good low-temperature fixability, heat-resistant storage stability, high-temperature offset resistance, small particle size and sharp particle size distribution. During the toner manufacturing process, a crystalline polyester resin is dissolved by heating in an organic solvent, and the resulting solution is cooled to recrystallize the crystalline polyester resin. A crystalline polyester dispersion in which the amorphous polyester resin is dissolved in the dispersion and pulverized to form fine particles, and the volume average particle size of the crystalline polyester resin is 0.1 to 1.0 μm.
