Abstract: A method for producing a toner includes a step (1) of forming resin microparticles in an aqueous medium in the presence of a surfactant, a step (2) of aggregating the resin microparticles to form aggregated particles, and a step (3) of heating and the aggregated particles and allowing the aggregated particles to coalesce to form toner particles, in which a resin component in the resin microparticles contains an olefinic copolymer and resin A, the resin A has an acid value of 1 mgKOH/g or more and 50 mgKOH/g or less, the resin A has a SP value of 19.0 (J/cm3)0.5 or more and 21.0 (J/cm3)0.5 or less, and the resin component has an olefinic copolymer content of 50% by mass or more with respect to the total mass of the resin component.

Abstract: A toner includes a toner particle containing a resin component. The resin component contains an ester group-containing olefin copolymer and an acid group-containing olefin copolymer. For example, the ester group-containing olefin copolymer is an ethylene-vinyl acetate copolymer, and the acid group-containing olefin copolymer is an ethylene-methacrylic acid copolymer. The acid group-containing olefin copolymer has an acid value of 50 to 300 mg KOH/g. The content of the ester group-containing olefin copolymer in the resin component is 50 mass % or more based on the total mass of the resin component. The content of the unit derived from the vinyl acetate is 3 mass % or more and 35 mass % or less based on the total mass of the ester group-containing olefin copolymer.
