Abstract
In differential scanning calorimetry of a toner, regarding a binder resin in the toner, (i) the peak temperature Tof a maximum endothermic peak (temperature raising rate 10.0° C./min; P) is 50° C. to 80° C. and the half-width Wis 2.0° C. to 3.5° C. and (ii) W, W, and Wsatisfy that W/Wis 0.20 to 1.00 and W/Wis 1.00 to 1.50, where the half-width of a maximum endothermic peak (temperature raising rate of 1.0° C./min; P) is represented by W(° C.) and the half-width of a maximum endothermic peak (temperature raising rate of 20.0° C./min; P) is represented by W(° C.).
