    摘要: An image forming apparatus for performing a copier job and a printer job includes a controller operatively connected to a fixing rotary body heater and a pressing rotary body heater to control the fixing rotary body heater and the pressing rotary body heater. The controller activates a standby mode after the copier job and the printer job are finished in which the controller turns off at least the fixing rotary body heater and a subsequent off mode in which the controller turns off the pressing rotary body heater and the fixing rotary body heater, and identifies which of the copier job and the printer job is to be performed to turn on and off the pressing rotary body heater in the standby mode according to the identified job.

    摘要: A fixing device includes a fixing member including a heating unit, and a pressure member, the heating unit includes a sub-heater having a heat generating portion in a region smaller than a minimum paper width, a main heater having a heat generating portion at outside of the sub-heater, a first temperature detector to detect a temperature of the fixing member at the heat generating portion of the main heater, and a second temperature detector to detect the temperature at the heat generating portion of the sub-heater. The main heater and the sub-heater can be switched selectively, and the initial duty ratio at the start of PID temperature control by the sub-heater is determined in accordance with a difference between temperatures detected by the respective temperature detectors at the start of PID temperature control and a target temperature so that the temperature is not overshooting and dropped.
