Abstract:
A method for producing a toner for electrostatic image development, including the steps of (1) polycondensing an alcohol component, a carboxylic acid component, and polyethylene terephthalate to provide an amorphous polyester; and (2) subjecting the amorphous polyester obtained in the step (1) and components containing a crystalline polyester in an amount of from 0.3 to 2.5 times the mass of the components derived from the polyethylene terephthalate in the amorphous polyester to a process for producing a toner. The toner for electrostatic image development obtained by the method of the present invention is suitably used in development or the like of latent images formed in, for example, an electrophotographic method, an electrostatic recording method, an electrostatic printing method, or the like.
