An object of the present invention is to provide a method for efficiently producing a toner containing, as a binder resin, a crystalline polyester resin having excellent low-temperature fixability and easy control of thermal characteristics and charging characteristics. In a toner excellent in low-temperature fixability obtained by formulating a crystalline polyester resin, the crystalline polyester resin in the toner is sufficiently crystallized and melted by internally adding a fatty acid metal salt to the toner. At the same time as improving the productivity of the rolling process after kneading, it is possible to provide a method for producing a toner in which thermal characteristics and charging characteristics can be easily controlled as compared with the prior art.
