A toner that is excellent in low-temperature fixability at the time of high-speed printing, achieves both hot offset resistance and winding resistance, and has such satisfactory durability as not to be liable to cause an image failure even at the time of long-term endurance. The toner includes a toner particle containing a binder resin including a first resin and a second resin, wherein the first resin is a crystalline resin, wherein the second resin is an amorphous resin, wherein, the toner has a domain-matrix structure formed of: a matrix containing the first resin; and domains each containing the second resin, wherein, an endothermic quantity ΔH (J/g) derived from the first resin satisfies a relationship of ΔH≥3, and wherein, in flow tester measurement of the toner, the following relationships are satisfied: T10≥65; T1−T10≤10.
