    摘要: An image forming apparatus is provided. The image forming apparatus includes an image forming unit; a fuser having a heating unit to which an alternating voltage is applied from an alternating power supply so as to perform heating; a zero-cross pulse generating unit that generates a zero-cross pulse; a voltage estimating unit that estimates the alternating voltage on the basis of a width of the zero-cross pulse; a temperature detecting unit that detects the temperature of the fuser; a heating control parameter setting unit that sets a heating control parameter for controlling the heating unit on the basis of the alternating voltage estimated by the voltage estimating unit and the temperature of the fuser; and a heating control unit that controls the heating unit on the basis of the heating control parameter set by the heating control parameter setting unit.
