Abstract
A fixing apparatus including a rotation detection circuit which detects the rotation state of the rotating member or pressing member, and one to (N−1) limiting circuits which limit driving of one to (N−1) driving circuits in accordance with an output from the rotation detection circuit, wherein when the rotation detection circuit detects that the rotating member or pressing member is not rotating, the one to (N−1) limiting circuits limit driving of the one to (N−1) driving circuits in accordance with the output from the rotation detection circuit to suppress energization of the heating elements regardless of the driving signals from the control unit to the driving circuits.
