Toner for electrophotography
A toner for electrophotography obtained by a method including: step 1: mixing a polyester and a polylactic acid at a temperature of 140° C. or higher and 200° C. or lower and subjecting the mixture to a transesterification reaction to provide a resin composition; and step 2: mixing the resin composition obtained in step 1 with a polyester which is identical to and/or different from the polyester of step 1, and a method for producing the toner. The toner for electrophotography of the present invention is suitably used in developing latent images formed in an electrophotographic method, an electrostatic recording method, an electrostatic printing method, or the like.
