发明名称 ELECTROPHOTOGRAPHIC TONER
摘要 PROBLEM TO BE SOLVED: To provide an electrophotographic toner excellent in low temperature fixability, hot-offset resistance under high temperature and high humidity, and suppression of fogging under high temperature and high humidity.SOLUTION: An electrophotographic toner comprises: a binder resin including a crystalline composite resin C and an amorphous polyester A; and hydrocarbon wax. The crystalline composite resin C comprises: 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. In the electrophotographic toner, mass ratio (amorphous polyester A/crystalline composite resin C) of the amorphous polyester A to the crystalline composite resin C is 60/40 or more and 95/5 or less, and the amorphous polyester A is provided in which content of an amorphous polyester AL obtained by performing condensation polymerization of an alcohol component where content of ethylene oxide addition product of bisphenol A is 55 mol% or more and a carboxylic acid component is 50 mass% or more of the amorphous polyester A.SELECTED DRAWING: None
