Abstract
Provided is a toner having a toner particle that contains a binder resin, a colorant, a wax, and a crystalline polyester, wherein two or more peak tops for crystallization peaks are present in a temperature range from 40° C. to 80° C. in a first DSC curve obtained by a process or cooling the toner from 100° C. to 20° C. at 0.5° C./min, and using ΔH(0.5) for the exothermic quantity for the peak on the lowest temperature side of these crystallization peaks and using ΔH(100) for the exothermic quantity of the crystallization peak on the lowest temperature side in a second DSC curve obtained by a process of cooling the toner from 100° C. to 20° C. at 100° C./min, the ratio [ΔH(100)/ΔH(0.5)] is at least 2.0 and not more than 6.0.
