Abstract: A toner comprising a colorant, a release agent, an amorphous polyester, and a crystalline polyester having an endothermic peak temperature of 60 to 80° C. and an endothermic quantity of 3.0 to 20.0 J/g. The endothermic peak temperature is determined from a constant rate component curve of the crystalline polyester obtained in a second heating of temperature-modulated differential scanning calorimetry. The endothermic quantity is determined from an area between the constant rate component curve and its base line drawn between 0 and 100° C., within a temperature range of 0 to 50° C.
