摘要： A fixing apparatus has first and second heating members and a current control unit which controls a number of waves and each of a first AC current to the first heating member and a second AC current to the second heating member in a positive-negative symmetrical pattern by a unit of predetermined number of half-waves. Regardless of a duty ratio of the first heating member and the second heating member, when the current control unit controls a number of waves so that the second AC current is larger than the first AC current in the first duty ratio, the current control unit controls the number of waves so that the first AC current is larger than the second AC current in a second duty ratio adjacent to the first duty ratio.
