    摘要： An image forming apparatus and a controlling method thereof. The image forming apparatus includes a fixing member having a heating source to heat a developer of a recording medium, a power supply unit to the heating source, first and second temperature sensors for respective first and second positions on the fixing member, a width sensor for the recording medium, and a control unit, when a difference between the first temperature and the second temperature is greater than a predetermined reference value, determining whether the first temperature is abnormal based on the width of the recording medium and, when the first temperature is abnormal, interrupting the power supply to the heating source. An error in the temperature sensor is determined when a temperature difference between the first and second position of the fixing member is greater than a predetermined degree and the recording medium passes through both temperature sensors.

    摘要： A projection lens system that has a compact configuration and is capable of correcting a color aberration. In the system, first and second lenses have a weak refractive power, respectively, and a third lens has a strong positive refractive power. A fourth lens corrects an aberration generated by the third lens, and a fifth lens has a negative refractive power. A diffractive optical element is formed on at least one among the surface of the first to fifth lenses. A color aberration and spherical aberration is corrected with the diffractive optical element, so that a high resolution can be realized without increasing the number of lenses and the manufacturing cost can be reduced.
