The toner includes toner particles, each of which contains a binder resin, a colorant, and a wax. The toner has a softening point of 75° C. or more and 110° C. or less measured by a constant-pressure-extrusion-type capillary rheometer. The wax is a hydrocarbon wax composed of a hydrocarbon compound. The hydrocarbon wax has specific abundance ratios each corresponding to a specific carbon number range of hydrocarbon compounds.
