Abstract: Provided are a polyester resin composition from which an electrophotographic toner having excellent charge amount, excellent electrostatic stability, excellent low-temperature fixing property, and excellent resistance to offset can be obtained, and an electrophotographic toner containing the polyester resin composition. Specifically, provided are a polyester resin composition for an electrophotographic toner, containing a polyester resin (A) which is obtained by reacting a monobasic acid (a1), a polybasic acid (a2), a polyhydric alcohol (a3), a monoepoxy compound (a4), and a polyepoxy compound (a5) having four or more epoxy groups, and an electrophotographic toner containing the polyester resin composition for an electrophotographic toner.

Abstract: Use of a polyester resin obtained by reacting a divalent or higher epoxy compound, a dibasic or higher polybasic acid compound selected from a polybasic acid and/or acid anhydride and/or lower alkyl ester thereof, and a divalent or higher polyvalent alcohol in a toner for electrostatic charge development containing at least a binder resin, a colorant, and a charge control agent can provide a toner for a non-magnetic single component development having excellent fixing properties, offset resistance and development durability.
