In the measurement of an endothermic amount of a toner, (1) an endothermic peak temperature (Tp) derived from the binder resin is 50° C. or higher and 80° C. or lower; (2) a total endothermic amount (ΔH) derived from the binder resin is 30 [J/g] or more and 125 [J/g] or less based on mass of the binder resin; (3) when an endothermic amount derived from the binder resin from an initiation temperature of an endothermic process to Tp is represented by ΔH Tp [J/g], ΔH and ΔH Tp satisfy formula (1) below; and (4) when an endothermic amount derived from the binder resin from the initiation temperature of an endothermic process to a temperature 3.0° C. lower than Tp is represented by ΔH Tp-3 [J/g], ΔH and ΔH Tp-3 satisfy formula (2) below. n 0.30≦Δ H Tp /ΔH ≦0.50 (1)n n 0.00≦Δ H Tp-3 /ΔH ≦0.20 (2) |
