Abstract
A toner is provided. The toner comprises a binder resin, a colorant, and a release agent. The toner satisfies the following relations (1) and (2):3.0×10'(50)/′(80)  (1)(10)≥75 degrees C.  (2)where G′(50) represents a storage elastic modulus at 50 degrees C., G′(80) represents the storage elastic modulus at 80 degrees C., and T(10) represents a temperature at which the storage elastic modulus is 10Pa or higher during a temperature fall from 100 degrees C. to 30 degrees C., in a measurement of dynamic viscoelasticity of the toner.
