ABSTRACT:
The toner for developing an electrostatic charge image comprises a colorant, a binding resin and a resin copolymer of aliphatic hydrocarbon and aromatic hydrocarbon having 9 or more of carbon atoms. Preferably, the toner further comprises a wax. The endothermic peak of the wax at DSC is preferably from 70 to 100.degree. C. The petroleum resin copolymer preferably has a ring and ball softening point of from 80 to 170.degree. C., and the binding resin is preferably a polyester resin. The weight ratio of the aromatic hydrocarbon monomer and the aliphatic hydrocarbon monomer of the petroleum resin copolymer is preferably from 99:1 to 50:50.
