    摘要： A fixation temperature control device is to be applied to a copying machine or the like. A control section determines a heat roller control temperature (T P-H ) in consideration of a detected press roller temperature (T P2 ). When the heat roller temperature (T P1 ) is lower than a reference temperature (T PTH ), a correction value (E1) is added to a heat roller reference temperature (T HCON ) to set the heat roller control temperature (T P-H ) higher than usual. When a fixing unit (35) is in a stand-by status and the press roller temperature (T P2 ) is in a temperature range between 80°C and 90°C, a heat roller (38) and a press roller (37) are preferably rotated at a speed lower than a usual rotational speed.

    摘要： A fixation control device is provided which controls the operation of a fixing unit (35) having a heat roller (37) and a press roller (38) between which a sheet (4A, 4B, 4C, 4D) is passed. When copies are successively made on a plurality of narrow-size sheets (4A, 4B, 4C, 4D), the temperature of the end portions of the press roller (38) rises and, therefore, the difference between the temperatures of the end portions and the central portion of the press roller (38) becomes greater. The greater temperature difference results in a diameter difference between the central portion and the end portions of the press roller (38) due to thermal expansion, thereby reducing sheet transportation ability of the heat roller (37) and press roller (38). However, the fixation control device of the present invention can compensate the reduction in the transportation ability by increasing the rotational speed of the heat roller (37) and press roller (38) when the temperature difference becomes greater.
