Abstract
Provided is a toner containing a binder resin, wherein the binder resin contains an amorphous polyester and a crystalline polyester, and wherein, when the toner is used as a sample in differential scanning calorimetry (DSC) involving a first process of increasing a temperature from 20° C. to 180° C., a second process of decreasing the temperature from 180° C. to 20° C., and a third process of increasing the temperature from 20° C. to 180° C., DSC curves have a specific endothermic peak or exothermic peak derived from the crystalline polyester, and when a temperature of a maximum peak top of the endothermic peak in the DSC curve obtained through the first process is represented by T1 (° C.), and a temperature of a maximum peak top of the endothermic peak in the third DSC curve is represented by T2 (° C.), the Tl and the T2 satisfy the following expression (1).
