ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, METHOD FOR PRODUCING SAME, IMAGE FORMING METHOD AND IMAGE FORMING DEVICE

PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which does not stain even a recorded image, a high-speed image forming device which uses the toner, does not form a diffused image or the like and ensures high image quality and an image forming method. SOLUTION: The electrostatic charge image developing toner comprises a resin composition for the toner consisting essentially of a bonding resin and a release agent and a colorant. The resin composition is produced by carrying out the polymerization of the bonding resin in the presence of the release agent. The toner is produced through a melt kneading step in which the maximum kneading temperature Tk ( deg.C) applied to the resin composition, the softening point Tb ( deg.C) of the resin composition and the melting point or softening point Tw ( deg.C) of the release agent satisfy the relation of Tw
