Abstract:
A toner comprising a toner particle containing a resin and a colorant, wherein, with respect to a temperature-storage elastic modulus curve obtained by powder dynamic viscoelastic measurement on the toner, (I) the relative minimum values for the variation in the storage elastic modulus E′ with respect to temperature T in the temperature range of at least 30° C. and not more than 180° C. have a relative minimum value of equal to or less than −1.00×107 and the relative minimum value on the lowest temperature side is equal to or less than −1.00×108; (II) the storage elastic modulus E′ (50) of the toner at 50° C. is at least 1.00×109 and not more than 9.00×109; and (III) for a storage elastic modulus E′ (120) of the toner at 120° C., E′ (50) and E′ (120) satisfy 1.50≤[E′ (50)]/[E′ (120)]≤3.00.
