Abstract

PURPOSE:To reduce the overshoot easily caused at the time of a high voltage, and to prevent adverse fixing easily caused at the time of a low voltage by controlling the heat generating maximum continuous time and the heat generating stop time of an electric heat generating body according to the size of the voltage of a power source. CONSTITUTION:On an image forming device corresponding to the wide ranged voltage whose allowable maximum voltage of the power source voltage is more than twice of the allowable minimum voltage, the heat generating maximum continuance time and the heat generating stop time of the electric heat generating body 5 are changed and set adequately according to the power voltage at the time when the temperature of the heating means like the heating roller 19 before fixing processing is rising or at the time of fixing action. The overshoot easily caused at the time of the high voltage can be reduced and the adverse fixing easily caused at the time of the low voltage can be prevented. And the image forming device which has the simple construction, whose cost of production is less expensive, and which corresponds to the wide range voltage whose allowable maximum voltage of the power voltage is more than twice of the allowable minimum voltage can be obtained.
