摘要： This invention can provide a fixing apparatus capable of determining its own life with high accuracy, and an image forming apparatus using this fixing apparatus. To accomplish this, a fixing apparatus includes a fixing unit whose nip portion is separable, a fixing driving motor which drives the fixing unit, a load detecting unit which detects the load acting on the fixing driving motor, and a determining unit which determines the life of the fixing unit on the basis of the difference between the load while the fixing unit is in a press-contacted state and the load while the fixing unit is in a separated state, which are detected by the load detecting unit.

摘要： An image forming apparatus which can individually detect contact fusion of relays in a circuit configuration in which the relays are connected to respective both ends of a fixing heater. A first relay and a second relay are each connected between a power source and the fixing heater. The presence or absence of an input voltage to the fixing heater is detected on paths from the first relay to the fixing heater and from the second relay to the fixing heater. When the input voltage is detected in a state in which the first relay is on and the second relay is off, it is determined that the second relay has failed. When the input voltage is detected in a state in which the first relay is off and the second relay is on, it is determined that the first relay has failed.
