Summary:To provide a toner that is excellent in low-temperature fixability, electrification maintainability, and scratch resistance.SOLUTION: A toner has a toner particle containing a binder resin and wax. The binder resin contains an amorphous polyester resin, a polymer A, and a component B. The content of the amorphous polyester resin in the binder resin is 50.0 mass% or more. The polymer A has a first monomer unit and a second monomer unit represented by the following formula (C). In the formula (C), RZ3 represents a hydrogen atom or a methyl group, and R represents an alkyl group having 18 to 36 carbon atoms. The content ratio of the first monomer unit in the polymer A is 5.0 to 60.0 mol%.SELECTED DRAWING: None 【課題】低温定着性、帯電維持性、及び耐擦過性に優れたトナーを提供すること。【解決手段】結着樹脂及びワックスを含有するトナー粒子を有するトナーであって、結着樹脂は非晶性ポリエステル樹脂、重合体Ａ及び成分Ｂを含有し、結着樹脂中の非晶性ポリエステル樹脂の含有量は５０．０質量％以上であり、重合体Ａは下記式（Ｃ）で表される第一モノマーユニット及び第二モノマーユニットを有し、式（Ｃ）中、ＲＺ３は、水素原子又はメチル基を表し、Ｒは、炭素数１８〜３６のアルキル基を表し、重合体Ａ中の第一モノマーユニットの含有割合が５．０〜６０．０モル％である。【選択図】なし
