Abstract
The present invention provides a toner that exhibits an excellent low-temperature fixability and an excellent ejected paper adhesiveness during high-speed printing, without affecting the long-term storage stability, in which the toner has a toner particle that contains a resin component, wherein the toner has, in a DSC curve measured with a differential scanning calorimeter, a glass transition temperature of at least 50° C. and not more than 65° C. and a cold crystallization peak during cooling of at least 40° C. and not more than 70° C., and has an endothermic peak in a DSC curve measured with a differential scanning calorimeter for the resin component of at least 70° C. and not more than 95° C.
