Abstract
A method for producing a toner for electrostatic image development containing at least an amorphous polyester and a crystalline polylactic acid, including step 1: mixing an amorphous polyester and a crystalline polylactic acid at a temperature of from 140° to 250° C.; step 2: melt-kneading a mixture obtained in the step 1; and step 3: pulverizing and classifying a melt-kneaded product obtained in the step 2; and a toner for electrostatic image development obtainable by the method. The toner for electrostatic image development obtainable by the method of the present invention is suitably used in development or the like of latent images formed in an electrostatic development method, an electrostatic recording method, an electrostatic printing method, or the like.
