摘要： A fixing unit fixes a developing material deposited on a recording medium by heating and pressing the recording medium. The fixing unit includes two heating members that apply heat to the recording medium and two temperature-sensitive shutoff devices. The two temperature-sensitive shutoff devices are connected in series with a corresponding one of the heating members. Each of the temperature-sensitive shut-off devices includes a first heat-sensitive shut-off element and a second heat-sensitive shut-off element. The first heat-sensitive shut-off element shuts off electric power to the corresponding one of the two heating members when a temperature of a surface of the corresponding one of the two heating members exceeds a certain value. The second heat-sensitive shut-off element shuts off electric power to the corresponding one of the two heating members when a temperature of a surface of the second one of the two heating members exceeds a certain value.

摘要： A fixing unit fixes a developing material deposited on a recording medium by heating and pressing the recording medium. The fixing unit includes a first number of heating members that apply heat to the recording medium and a second number of switches that supply electric power to the first number of heating members. Each of the heating members receives electric power through a series circuit of the switches. Each of the switches responds to a surface temperature of a corresponding one of the heating members so that when the surface temperature exceeds a predetermined value, the electric power is shut off.
