Abstract:
A fixing apparatus comprising:a fixing body and a pressure body which are pressed against each other and rotate; fixing body heating means for heating said fixing body upon receiving supply of power from a power supply; pressure body heating means for heating said pressure body upon receiving supply of power from said power supply; temperature detecting means for detecting a temperature of at least one of said fixing body and said pressure body; and controlling means for controlling supply of power from said power supply to said fixing body heating means and said pressure body heating means in such a manner that a temperature detected by said temperature detecting means becomes a predetermined set temperature, wherein an unfixed image is fixed on a recording medium for bearing the unfixed image by pinching and conveying the recording medium by using said fixing body and said pressure body, and wherein by said controlling means, electric energy per a predetermined time supplied from said power supply to said pressure body heating means is set to a predetermined quantity or a lower quantity by setting a value of a voltage from said power supply to said pressure body heating means so as to be small as a width of the recording medium to be subjected to fixation in a direction orthogonal to a conveying direction is decreased.
