Abstract:
An electrostatic image developing toner includes toner particles that contain coloring particles containing a binder resin, a coloring agent and a releasing agent. The binder resin includes an amorphous resin and a crystalline polyester resin. The toner satisfies Relations (1) and (2). ΔH1 is the amount of heat absorption based on a melting peak of the crystalline polyester resin in a first heating step. ΔH2 is the amount of heat absorption based on a melting peak of the crystalline polyester resin in a second heating step. ΔH0 is the value of the amount of heat absorption based on a melting peak of the crystalline polyester resin in the second heating step, multiplied by the ratio of the crystalline polyester introduced in the electrostatic image developing toner. 0.43
