    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.

    摘要： A fixing device includes a rotatable, endless belt, a stationary heater, a stationary pad, a rotatable pressure member, and a heat conductive member. The rotatable, endless belt is looped into a generally cylindrical configuration. The stationary heater is disposed inside the loop of the belt to radiate heat to the belt. The stationary pad is disposed inside the loop of the belt. The rotatable pressure member is disposed parallel to the stationary pad with the belt interposed between the pressure member and the stationary pad. The pressure member presses against the stationary pad via the belt to form a fixing nip therebetween through which a recording medium passes. The heat conductive member is interposed between the belt and the heater to transfer heat radiated from the heater by conduction therethrough to the belt.

    摘要： Heat-equalizing rotation of a fixing member and a pressing member for equalizing the distribution of the temperature of a surface of the fixing member in a width direction is performed after a recording medium having a size less than or equal to a predetermined size in the width direction passes a nip portion and before a recording medium having a size greater than the predetermined size in the width direction passes the nip portion. Further, a termination condition of the heat-equalizing rotation is selected from among a plurality of different kinds of termination conditions, based on image formation related information related to next image formation performed after the heat-equalizing rotation.
