PROBLEM TO BE SOLVED: To provide a molding mold for a magnet roller by which the temperature difference among a plurality of temperature adjusting jackets arranged around a cavity and independently temperature-controlled can be reduced and the warpage of the magnet roller can be minimized. SOLUTION: The cavity of the molding mold for the magnet roller is arranged so that its center axial line is vertically oriented. A gate is located to the upper end or the lower end of the cavity. A runner is constituted by including a horizontal route part directed toward the center axial line of the cavity. The relative arrangement of a magnetic field forming means to the horizontal route part is set so that the magnitude of the warpage of the magnet roller molded under the uniform temperature distribution in the circumferential direction of the cavity is minimized.
