Abstract:
A toner in which, in a loss tangent (tan δ) curve obtained by a dynamic viscoelasticity test, the tan δ shows a maximal value δa in the temperature region of 28.0-60.0° C., which maximal value δa is 0.50 or more, and shows a minimal value δb in the temperature region of 45.0-85.0° C., which minimal value δb is 0.60 or less, where the difference between the maximal value δa and the minimal value δb is 0.20 or more; and, where the temperature that affords the maximal value δa is represented by Ta(° C.) and the temperature that affords the minimal value δb is represented by Tb(° C.), the difference between the Ta and the Tb is 5.0-45.0° C.; and the toner having, in a storage elastic modulus (G′) curve obtained by the dynamic viscoelasticity test, a value G′a of a storage elastic modulus at the Ta, of 1.00×106-5.00×107 Pa.
