PROBLEM TO BE SOLVED: To provide a method of manufacturing toner easily reducing residual monomer without impairing necessary functions as toner with a simple structure without requiring special facilities/apparatus, and to thereby provide the toner having high safety and mitigating the problem of odor. SOLUTION: A pulverized material is used as the binder resin for toner, which is obtained by performing once or more times the at least two steps including a melt kneading step of melting and kneading a raw material resin by a biaxial kneading machine or the like and a pulverizing step of cooling the molten kneaded mixture obtained by the melt kneading step and pulverizing it by a jet mill pulverizer or the like so that the particle size of the pulverized material is≤10μm. Thus, the residual monomer derived from the binder resin in the toner is reduced, and the toner having high safety and mitigating the problem of odor is obtained. COPYRIGHT: (C)2009,JPO&INPIT
