    • A heat-fixing device includes a heat plate along which a transfer medium bearing thereon a toner image is advanced during which the toner image becomes fixed to the transfer medium by fusing, the heat plate including a plurality of heating sections arranged along the direction of advancement of said transfer medium each of the heating sections being provided with at least one electrical heater. The device also includes a control circuit for controlling the operation of the heaters such that, under a non-steady-condition, only selected ones of the heaters are set in operation thereby only the corresponding heating sections are positively heated; whereas, under a steady-state condition, all of the heaters are operated at the same time thereby maintaining all of the heating sections at a predetermined temperature.
    • 热定影装置包括加热板,在其上带有调色剂图像的转印介质沿着该加热板前进,在此期间调色剂图像通过定影固定到转印介质上,该加热板包括沿着前进方向布置的多个加热部分 的所述转印介质,每个加热部分设置有至少一个电加热器。 该装置还包括用于控制加热器的操作的控制电路,使得在非稳定状态下,只有选择的加热器被设置在操作中,从而只有对应的加热部分被正确地加热; 而在稳态条件下,所有的加热器都在同一时间运行,从而将所有加热部分保持在预定的温度。
