Abstract
To provide a toner for developing electrostatic images which is not easily cause the phenomenon of toner-spent, constituent materials are so selected that a charge control resin has hardness which is the same as the hardness of a binder resin or the charge control resin is harder than the binder resin, as measured with a scanning probe microscope in a viscoelasticity evaluation mode in respect to the binder resin and the charge control resin which are present in the particle interiors or particle surfaces of the toner.
