ABSTRACT:
A fixing apparatus which is equipped with a heat roller that has a resistance heating member generating heat by means of current supply and which is constructed such that current is supplied to the resistance heating member from the power source through a power supply member electrically connected to the resistance heating member, wherein abnormal temperature increases in the heat roller and in the power supply member can be prevented separately, as well as a control method for the fixing apparatus. The fixing apparatus detects the temperature of the heat roller and the temperature of the power supply member, and then stops the supply of current to the resistance heating member when the temperature of the heat roller is higher than a predetermined temperature for the heat roller or the temperature of the power supply member is higher than a predetermined temperature for the power supply member.
