The present invention relates to a toner for electrostatic image development, obtainable by a process including the steps of (I) melt-kneading a raw material mixture comprising a resin binder, a releasing agent, and a colorant; cooling the melt-kneaded mixture; and pulverizing the cooled mixture; and (II) further pulverizing a pulverized product obtained in the step (II) in the presence of an external additive; and classifying the pulverized product, wherein the releasing agent in the step (I) contains a wax having a melting point of from 65° to 100° C., and wherein the external additive in the step (II) contains specified inorganic oxides. The toner of the present invention can be suitably used, for instance, for the development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method or the like.
