摘要:
An image forming apparatus includes image forming means for forming an unfixed image on a recording material; a fixing device for heat-fixing the unfixed image on the recording material, the fixing device including a heater for heating the unfixed image, the heater being controlled at a predetermined temperature during a fixing operation, and a temperature detecting element for detecting the temperature of the heater, wherein power supply to the heater is started after production of image formation start signal; and a discriminating device for discriminating an error in the fixing device on the basis of the temperature of the heater a predetermined period after start of power supply to the heater.
