PROBLEM TO BE SOLVED: To efficiently crosslink a polyester resin in a short time, to secure a sufficient elastic modulus at a high temperature without using a conventional polyester cross-linking agent, to solve problems of offset and excessive gloss, and to crease Provided is a toner manufacturing method capable of obtaining a toner without partial toner peeling, that is, fixing strength deficiency. A polyester resin obtained by condensation of a polyhydric alcohol and a polycarboxylic acid, wherein the polyhydric alcohol contains an unsaturated polyhydric alcohol or the polyhydric carboxylic acid contains an unsaturated polyhydric carboxylic acid. Dispersing the polyester resin in an aqueous medium to prepare a polyester resin particle dispersion, and adding a radical polymerization initiator to the polyester resin particle dispersion to cause a radical polymerization reaction, the resulting polyester resin particle dispersion Adjusting the process.
