Toner for development of electrostatic charge image and method for producing the same

The present invention relates to a toner for development of electrostatic images for developing electrostatic latent image s formed by an electrophotographic process, electrostatic recording process or the like, and a production process thereof. A toner for development of electrostatic images, comprising at least a binder resin, a colorant and a charge control agent, wherein the charge control agent is a polar resin composed of a copolymer of a vinyl monomer and SOX (X=H or alkali metal) group-containing (meth)acrylamide and having an SOX group-containing (meth)acrylamide unit content of 0.1 to 10 wt. % and a weight average molecular weight of 17,000 to 25,000, and a production process of the toner.
