ABSTRACT:
The invention provides a method for producing a toner comprising: a step of preparing a powder for production of the toner from a raw material containing a resin as a main component, a coloring agent, and a crystalline polyester having higher crystallinity than the resin as an accessory component, and a thermal conglobation step of conglobating the powder for production of the toner with heat. The invention also provides a method for producing a toner from a kneaded material obtained by kneading a raw material containing a resin and a coloring agent, wherein the resin comprises at least a first polyester resin and a second polyester resin different from the first polyester resin, and wherein when the coefficient of static friction of the first polyester resin is taken as μ1, the coefficient of static friction of the second polyester resin as μ2, the softening point of the first polyester resin as Ts1(° C.) and the softening point of the second polyester resin as Ts2(° C.), the relationship μ1>μ2and the relationship Ts1>Ts2are satisfied.
