TONER FOR DEVELOPMENT OF ELECTROSTATIC CHARGE IMAGE AND METHOD FOR PRODUCING THE SAME

摘要

A toner for development of electrostatic charge image comprising a binding resin, a colorant and an electrostatic charge controlling agent, characterized in that the charge controlling agent comprises a copolymer of a vinyl monomer with a SO3X (wherein X is H or an alkyl metal) group-containing (meth)acryl amide, wherein the content of SO3X group containing (meth)acryl amide unit in the copolymer is 0.1 to 10 wt.%, and the charge controlling agent is a polar resin having a weight average molecular weight of 17,000 to 250,000, and the method for producing the same.
