摘要： To provide a positive charge control resin with which an electrophotographic functional component part coming into contact with a toner can be made chargeable in a polarity reverse to the polarity of the toner, and which has superior dispersibility in, and compatibility with, a main binder. The present invention is a positive charge control resin having a copolymer obtained by polymerizing specific acrylate or methacrylate monomer, amino-group-containing monomer(s) and carboxyl-group-containing monomer(s) as copolymerization components.
