PROBLEM TO BE SOLVED: To provide an electrophotographic toner excellent in low temperature fixability, durability, suppression of wrapping of paper during fixation.SOLUTION: An electrophotographic toner comprises: a binder resin including a crystalline resin and an amorphous resin; and a mold release agent. The crystalline composite resin comprises a crystalline composite resin C including: a polycondensation resin component which is obtained by performing condensation polymerization of an alcohol component containing an aliphatic diol having 9 or more and 14 or less carbon atoms and a carboxylic acid component containing an aliphatic dicarboxylic acid compound having 9 or more and 14 or less carbon atoms; and a styrene resin component. The amorphous resin comprises: a polycondensation resin component which is obtained by performing condensation polymerization of an alcohol component and a carboxylic acid component containing an aromatic dicarboxylic acid compound; and an amorphous polyester AP which is obtained by performing condensation polymerization of an amorphous composite resin AC containing the styrene resin component, the alcohol component, and the carboxylic acid component containing the aromatic dicarboxylic acid compound. In the electrophotographic toner, softening point of the amorphous polyester AP is higher than that of the amorphous composite resin AC, and difference of the softening points between the amorphous polyester AP and the amorphous composite resin AC is 10°C or more and 50°C or less.SELECTED DRAWING: None |
