摘要:
The invention provides a toner that is capable of low-temperature fixing even in high-speed electrophotographic processes while keeping the cleaning performance when used at high temperatures and the high-temperature storage stability. This toner having toner particles, each of which contains a binder resin and a colorant is characterized in that the temperature of Tp [° C.] when the loss elastic modulus obtained by dynamic viscoelastic measurements on the toner exhibits a maximum value in the temperature range from at least 30° C. to not more than 200° C., is from at least 40° C. to not more than 55° C., and in that, with G″(Tp) [Pa] being this maximum value, G″(Tp+15) [Pa] being the loss elastic modulus at the temperature of Tp+15 [° C.], and G″(Tp+30) [Pa] being the loss elastic modulus at the temperature of Tp+30 [° C.], G″(Tp), G″(Tp+15), and G″(Tp+30) satisfy prescribed relationships.
