<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner having superior resistance to aggregation by heat and showing proper fixing and offset characteristics over a wide temperature region and suitable for a method for heat roll fixing, and to provide a color electrostatic charge image developing toner, having superior color reproducibility and transparency and showing stable electrification behavior, even when the toner is used for continuous printing by which high quality images can be obtained. SOLUTION: The electrostatic charge image developing toner contains binder resin, a coloring agent, and a release agent, and the binder resin consists of polyester resin obtained by the reaction of (1) naphthalene dicarboxylic acid and/or its lower alkyl ester and (2) aliphatic polyhydric alcohol.</p> |
