WAX FOR ELECTROPHOTOGRAPHIC TONER, COMPOSITION FOR ELECTROPHOTOGRAPHIC TONER, AND ELECTROPHOTOGRAPHIC TONER

摘要

PROBLEM TO BE SOLVED: To provide a wax for an electrophotographic toner, which gives an electrophotographic toner excellent in low-temperature fixability, hot offset resistance and chargeability, and a resin composition for an electrophotographic toner and an electrophotographic toner containing the wax.SOLUTION: The wax for an electrophotographic toner is obtained by allowing a polyhydric alcohol (A) having 3 or more valances to react with a monocarboxylic acid (B) having an alkyl chain having 14 to 28 carbon atoms. The wax is obtained by allowing 0.25 to 0.75 mol of carboxyl groups included in the monocarboxylic acid (B) to react with 1 mol of an alcoholic hydroxyl group included in the polyhydric alcohol (A). A composition for an electrophotographic toner is provided, which comprises the above wax for an electrophotographic toner, a binder resin, and a colorant. An electrophotographic toner is provided, comprising the above composition.
