Abstract
According to a mode of the present invention, there is disclosed a fixing apparatus comprising a non-contact temperature detection section which detects a temperature by infrared rays radiated from a heating member, to made uniform a surface temperature of the heating member in an axial direction and a rotation direction based on first temperature information for detecting a temperature difference of the axial direction of the heating member and second temperature information for detecting the temperature difference of the rotation direction of the heating member.
Claims5
A heatfusing control method comprising:
- heating an outer peripheral surface of a heating member using a plurality of induction heating coils arranged outside the heating member;
- detecting first temperature information for detection of a temperature difference of an axial direction of the heating member and second temperature information for detection of a temperature difference of a rotation direction of the heating member using at least two non-contact temperature detection elements disposed for each induction heating coil or between the coils;
- and
- executing at least one of an axial direction temperature control to minimize the temperature difference of the axial direction of the heating member and a rotation direction temperature control to minimize the temperature difference of the rotation direction of the heating member based on the first and second temperature information.
