Patent ID: 7088937

Claim:
An image heating apparatus comprising: a first rotatable member for being heated by a first heater to heat an image on a recording material at a nip; a first sensor for detecting a temperature of said first rotatable member; a first controller for controlling an electric power supply to said first heater so as to maintain a detected temperature of said first rotatable member at a first target temperature, and for controlling an electric power supply phase upon start of electric power supply to said first heater; a second rotatable member for being heated by a second heater to heat the image on the recording material at the nip; a second sensor for detecting a temperature of said second rotatable member; a second controller for controlling an electric power supply to said second heater so as to maintain a detected temperature of said second rotatable member at a second target temperature, and for controlling an electric power supply phase upon start of electric power supply to said second heater; delaying means for delaying timing of start of electric power supply to said first heater so that the timing is later than a timing of start of electric power supply to said second heater, when the detected temperature of said first rotatable member is lower than the first target temperature, and the detected temperature of said second rotatable member is lower than the second target temperature.
