Abstract:
A toner particle production method has an annealing step that is performed after the preparation of a resin solution by the dissolution or dispersion, in an organic solvent, of a binder resin having a polyester resin as its major component and a block polymer having a polyester segment and a vinyl polymer segment, and the preparation of a resin particle dispersion in which resin particles are dispersed by a dissolution suspension method, wherein, in this annealing step, the temperature of the obtained resin particle dispersion is held for at least 60 minutes in the temperature range from TgA-15 (° C.) to TmA (° C.), and under the conditions of a temperature variation range of not more than 20° C. and a temperature variation rate of not more than 0.35° C./minute.
