Abstract
An image forming apparatus includes a fixing device including a heating roller heated by a fixing heater, a DUTY storage portion, a heater control portion, a number-of-times counting portion, a number-of-times determining portion, and a modifying portion. The DUTY storage portion stores a first DUTY table and a second DUTY table. The heater control portion reduces the consumption current of the fixing heater based on the first DUTY table when a total consumption current exceeds a setting current. The number-of-times counting portion counts the number of times the total consumption current has exceeded the setting current. The modifying portion causes the heater control portion to control the energization of the fixing heater based on the second DUTY table when the number-of-times determining portion determines that the number of times of excess exceeds a setting number of times.
