Abstract:
An image forming apparatus for forming an image, including a fixing device having a coil in a heating roller and causing the coil to generate a radio-frequency magnetic field, thereby producing an eddy current in the heating roller and fixing a developer image on a recording medium by means of self-heating of the heating roller based on an eddy current loss, the apparatus comprising:receiving means for receiving a voltage abnormality error signal from the fixing device; time-measuring means for measuring a reception time of the voltage abnormality error signal when the receiving means has received the voltage abnormality error signal; confirmation means for confirming whether the reception time measured by the time-measuring means exceeds a predetermined limit value; first control means for executing a control to ignore the voltage abnormality when the conformation means has confirmed that the limit value is not exceeded; and second control means for executing a control to perform an error process for the occurrence of voltage abnormality, when the confirmation means has confirmed that the limit value is exceeded.
