PROBLEM TO BE SOLVED: To provide a toner excellent in low-temperature fixability but excellent in heat-resistant storage stability and suppressed in fixability during long-term storage. In measuring the endothermic amount of toner, (1) The endothermic peak temperature (Tp) derived from the binder resin is 50 ° C. or higher and 80 ° C. or lower, (2) The total endothermic amount (ΔH) derived from the binder resin is 30 J / g or more and 125 J / g or less per 1 g of the binder resin. (3) When the endothermic amount from the endothermic start temperature derived from the binder resin to Tp is ΔH Tp [J / g], ΔH and ΔH Tp are expressed by the following formula (1) 0.30 ≦ ΔH Tp /ΔH≦0.50 (1) Satisfied, (4) When the endothermic amount from the endothermic start temperature derived from the binder resin to a temperature lower by 3.0 ° C. than Tp is ΔH Tp-3 [J / g], ΔH and ΔH Tp-3 are The following formula (2) 0.00 ≦ ΔH Tp-3 /ΔH≦0.20 (2) A toner characterized by satisfying [Selection figure] None |
