    摘要: An image forming apparatus includes a fixing member, a pressing member, heat generators, temperature detectors, a power source, and a heat controller. The heat generators include a first heat generator and second heat generators corresponding to an imaged area and a blank area, respectively, of a recording medium. The heat controller controls a power source according to data provided by the temperature detectors, such that a heating area of the fixing member heated by one of the second heat generators located adjacent to the first heat generator acquires a temperature of T1−ΔT, where T1 is a temperature corresponding to the imaged area higher than a temperature T2 corresponding to the blank area, and ΔT is a temperature lower than a difference between T1 and T2. The heat controller changes ΔT between when a first side thereof is printed upon duplex printing and upon single-sided printing.
