A fixing apparatus that conveys a printing medium to a fixing nip portion formed by rotating members, and fixes an image onto the printing medium by heat from heating elements. The fixing apparatus also includes a safety element, a rotation detection circuit, and a limiting circuit. The safety element is in a power supply path to supply electrical power to the heating elements and to shut off the path in response with an abnormal temperature. The rotation detection circuit detects a rotation state of the rotating members. The limiting circuit limits a drive of a second driving circuit per a rotation detection circuit output. A first driving circuit detects that the circuit drives a first heating element per a control signal, regardless of the rotating members rotation state, and the second driving circuit drives a second heating element per a control signal and the output from the rotation detection circuit.
