摘要： An image forming apparatus includes a fixing device including a fixing member; a pressure member to press against the fixing member; and a halogen lamp to heat the fixing member, and a controller to control the halogen lamp. The controller controls an ON duty of the halogen lamp according to a control cycle, and sets the ON duty including two thresholds consisting of a first ON duty and a second ON duty that is larger than the first ON duty. The controller calculates an ON duty of the halogen lamp, judges whether the calculated ON duty is equal to or more than the first duty and less then the second duty, and changes the calculated ON duty when the calculated ON duty is equal to or more than the first duty and less then the second duty.
