Abstract: The toner according to the present invention is used for electrostatic latent image development, and has toner particles containing a binder resin, a colorant and a release agent. The binder resin is composed of a non-crystalline resin and a crystalline resin. The toner satisfies the relationship represented by specific expressions specified by the endothermic property of the crystalline resin, the endothermic property of the toner and the content ratio of the binder resin in the toner particles.
