ABSTRACT:
An electrostatic image developing toner comprises a binder resin which contains at least 60% by weight of a styrene-butadiene copolymer. The copolymer contains a component A having a molecular weight of at least 100,000 in an amount of at least 20% by weight relative to the binder resin, and a component B having a molecular weight of at least 500,000 in the component A is not more than 15% by weight relative to the binder resin. The toner has adequate flowability and noncoagulation property and is capable of forming a superior visible image in a contact heat fixing system.
