Abstract
The present invention is to provide a toner for developing electrostatic images having a low minimum fixing temperature, and high hot offset resistance and high heat-resistant shelf stability, and a method for producing the toner. Also, the present invention is to provide a toner for developing electrostatic images, comprising a binder resin, a colorant, a release agent and a retention aid, wherein the retention aid is a copolymer of 70 to 98% by weight styrene and 2 to 30% by weight (meth)alkyl acrylate, and the copolymer has a glass transition temperature of 5 to 60° C.
