Abstract
Provided is anon-magnetic toner including toner particles each containing at least a binder resin, a colorant, and a wax component, and an inorganic fine powder, in which: (1) when a temperature in a temperature range of 50 to 80° C. at which a loss tangent (tan δ) shows a maximum is represented by T1, a storage elastic modulus of the toner at the temperature T1 (G′(T1)) satisfies a relationship of 5.00×107≦G′(T1)≦1.00×109 (dN/m2); (2) a continuous temperature range with a width of 15° C. or more in which the loss tangent (tan δ) is 0.80 to 2.00 is present in the temperature range of 50 to 80° C.; and (3) the loss tangent (tan δ) is 1.00 or more in a temperature range of 120 to 160° C.
