    • An image forming apparatus includes a heat roller heated to a preset temperature; a pressure roller for having conductivity and forming a nip by pressure-contacting with the heat roller; a power supply unit to apply a bias voltage to the pressure roller; and a controller to, when a printing paper enters the nip, control the power supply unit to apply the bias voltage to the pressure roller. When a time interval is longer than a preset time, the controller can control the power supply unit not to apply the bias voltage when the printing paper is not placed in the nip, and when the time interval is shorter than the preset time, the controller can control the power supply unit to apply the bias voltage when the printing paper is not placed in the nip.
    • 图像形成装置包括加热到预设温度的加热辊; 用于通过与加热辊压力接触而具有导电性并形成辊隙的压力辊; 电源单元,用于向压力辊施加偏置电压; 以及控制器,当打印纸进入所述压区时,控制所述电源单元将所述偏置电压施加到所述加压辊。 当时间间隔长于预设时间时,控制器可以控制电源单元在打印纸没有放置在辊隙中时不施加偏置电压,并且当时间间隔短于预设时间时,控制器 可以控制电源单元在打印纸没有放置在压区中时施加偏置电压。

    • Provided is a semiconductor integrated circuit including an internal voltage generator for generating an internal voltage. A semiconductor integrated circuit includes a dividing unit, a comparing unit, a driving unit, and a voltage level controlling unit. The dividing unit divides an internal voltage in a predetermined division ratio to output a feedback voltage. The comparing unit compares a feedback voltage with a reference voltage. The driving unit drives an internal voltage terminal in response to an output signal of the comparing unit. The voltage level controlling unit controls a voltage level of the output signal of the comparing unit in response to a first control signal that is activated at a predetermined time before an operation time point of an internal circuit using an internal voltage.
