PROBLEM TO BE SOLVED: To provide a toner for developing an electrostatic image capable of exhibiting sufficient fixing separation performance even in an oilless fixing system and having excellent image quality (texture and fog on an image) and cleaning properties. A copolymer of at least a binder resin comprising a styrene copolymer resin, a colorant, a polyolefin wax, and an α-olefin-maleic anhydride copolymer-maleic anhydride monoester as a wax dispersant. And a toner containing The content of maleic anhydride in the copolymer is 5 to 15% by weight, the content of polyolefin wax is 10 to 25% with respect to the total amount of monomers constituting the binder resin, and the wax dispersant The content of is 10 to 60% with respect to the total amount of the polyolefin wax.
