Abstract:
A toner includes polyolefin and has an exothermic peak in a range from 40° C. to 70° C. in a cooling process of the polyolefin by the DSC after a first heating process of the polyolefin by DSC. The polyolefin does not have an exothermic peak in the cooling process of the polyolefin by the DSC after the first heating process of the polyolefin by the DSC, and has an exothermic peak in a range from 0° C. to 30° C. in a second heating process of the polyolefin by the DSC.
