ABSTRACT:
An electrostatic image developing toner useful for the formation of a toner image by electrophotographic process which employs a heat-fixing method by the use of a heat roller under pressure, wherein said toner comprises as the essential constituents a nonlinear polymer, a low-melting polymer which has a melting point of from 50.degree. to 130.degree. C. and which is incompatible with said nonlinear polymer, a copolymer composed of a segment polymer which is at least compatible with the above nonlinear polymer and a segment polymer which is at least compatible with said low-melting polymer and a coloring agent.
