摘要：
A method of producing a toner including at least a binder resin and a colorant. The method includes kneading a mixture including the binder resin and the colorant under pressure while injecting a supercritical fluid into the mixture upon application of heat to uniformly disperse the supercritical fluid in the mixture; depressurizing the mixture such that the mixture foams; cooling the mixture to prepare a kneaded mixture including air bubbles; and pulverizing the kneaded mixture.
