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.
