TONER

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 te.mperatures 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.
