Abstract
PURPOSE: To prevent over-heating of a heating roll by detecting the power supply time to an infrared ray heater at the warming up of the roll thereby carrying out peripheral temp. controlling.
CONSTITUTION: A heating roll 1 provided with an inrefrared ray heater 11 in a hollow metal cylinder, and a pressure roll 2 press-contacting the roll 1 over the lengthwise direction in parallel with the roll 1 are provided, and while a recording sheet S having powder toner images IT is being press-grasped and conveyed by the rolls 1 and 2, the toner images are fixed onto the sheet. The wall thickness of the cylinder of the roll 1 is made as thin as possible, the warming-up time of the roll 1 by the heater 11 is kept within one minute, the power supply time to the heater 11 is detected at the warming-up and the rise of the peripheral surface temp. of the roll is controlled, and after the warming-up, the peripheral temp. is controlled based on the temp. detected by a thermistor 3 contacting the roll 1.
