ABSTRACT:
An image forming apparatus includes a fixing unit that thermally fixes a toner image, a power control unit that controls a power supply from an auxiliary power supply to the fixing unit, a job-turnaround-time predicting unit that predicts a job turnaround time for executing an image forming job, a charging-time predicting unit that predicts a charging time for charging the auxiliary power supply, and a control unit that controls a charging operation for the auxiliary power supply and execution of the image forming job based on the job turnaround time predicted and the charging time predicted, such that the job turnaround time for the image forming job is minimized.
