Abstract:
Toner, including: a toner particle that contains a binder resin and a wax, wherein the binder resin includes an amorphous resin A, and, in dynamic viscoelasticity measurement of the toner, when the temperature at which the loss elastic modulus G″ measured at a frequency of 1 Hz becomes 1.00×106 Pa is set as T(1 Hz), when the temperature at which the loss elastic modulus G″ measured at a frequency of 20 Hz becomes 1.00×106 Pa is set as T(20 Hz), and when the maximum value of the ratio (tan δ) of the loss elastic modulus G″ with respect to the storage elastic modulus G′, measured at a frequency of 20 Hz, in a range of from 60° C. to 90° C. is set as tan δ(P), the toner satisfies T(20 Hz)−T(1 Hz)≤7.0° C., 0.80≤tan δ(P)≤1.90, 60° C.≤T(1 Hz)≤80° C., and 60° C.≤T(20 Hz)≤80° C.
