Abstract: A power supply control device including a chopper circuit generating a heater current for a halogen heater, a current feedback circuit generating a current feedback signal indicating a current amount based on an amount of the heater current, and a constant current circuit performing pulse-width modulation of the heater current amount according to a difference between a target heater current amount and the current amount indicated by the current feedback signal. The current feedback circuit switches between methods at least including a first method and a second method for generating the current feedback signal. The current feedback signal indicates a greater current amount with the first method than with the second method, and the current feedback circuit uses the first method during a period with a predetermined time length starting from when the halogen heater is turned on, and uses the second method after elapse of the period.

Abstract: An image forming apparatus forms decision registration mark for deciding whether or not a color registration correction for correcting color shifts in the color image carries out on an intermediate transfer belt. The decision registration mark is formed by registering four color registration marks. Color registration sensors detect a detection width of the decision registration mark along a sub scanning direction. A control portion receives the detection width of the decision registration mark and decides whether or not the color registration correction carries out based on whether or not the detection width of the decision mark detected by the detection portion exceeds the period of reference time. When the detection width of the decision mark detected by the detection portion exceeds the period of reference time, the control portion carries out the color registration correction.
