Abstract:
In a toner formed of toner particles which include a colorant, a wax, and a binder resin containing a crystalline resin (a) primarily composed of a polyester, the crystalline resin has an endothermic peak temperature (Tp) in a range of 50° C. to 80° C., and in a viscoelasticity measurement of the toner, G″(Tp−10) is in a range of 5.0×107 to 5.0×108 Pa, G″(Tp+10) is in a range of 5.0×105 to 5.0×106 Pa, and G″(Tp−20), G″(Tp−10), G″(Tp+10), and G″(Tp+30) satisfy specific relationships.
