A toner comprising: a toner particle containing a binder resin and a colorant; and an external additive, wherein the external additive is a composite particle having an organic substance and an organosilicon polymer coating layer on the surface of the organic substance, and when a curve for the variation (dE′/dT) in the storage elastic modulus E′ of the toner with respect to temperature T [° C.] is obtained on the basis of a curve of the temperature T—the storage elastic modulus E′ [Pa] of the toner, as determined by powder dynamic viscoelasticity measurements of the toner, the relative minimum value on the lowest temperature side between the onset temperature and 90° C. is −1.35×108 or less.
