Claim Text:
1. A toner, comprising: a resin binder, a releasing agent, and a charge control agent, wherein the resin binder comprises a polyester (A) obtained by polycondensing a carboxylic acid component comprising one or more succinic acid derivatives selected from the group consisting of succinic acids substituted with an alkyl group having 8 or more carbon atoms and 20 or less carbon atoms and succinic acids substituted with an alkenyl group having 8 or more carbon atoms and 20 or less carbon atoms, and an alcohol component, a content of the succinic acid derivative is 10% by mol or more and 30% by mol or less of a total amount of the raw material monomers of all the polyesters in the resin binder, and wherein the releasing agent comprises an α-olefin based polymer obtained by polymerizing monomers comprising an α-olefin having 26 or more carbon atoms and 28 or less carbon atoms in an amount of 95% by mol or more, and a content of the α-olefin based polymer is 0.5 parts by mass or more and 10 parts by mass or less, based on 100 parts by mass of the resin binder.
