Abstract
The present invention relates to an image heating apparatus, such as a heating fixing apparatus for fixing a toner image formed on plane paper. By making the width of a heat collecting plate of a thermoprotector for suppressing an excessive temperature rise of a heater provided in the apparatus, a failure in an image is suppressed irrespective of variations in the mounting position of the thermoprotector.
Claims5
An image heating apparatus comprising:
- a heater for heating an image formed on a recording material, said heater including a substrate and a heat generating resistor formed on said substrate;
- and
- a thermoprotector for suppressing an excessive temperature rise of said heater, said thermoprotector comprising a heat collecting portion contacting said heater,
- wherein a width of said heat collecting portion in a moving direction of the recording material is larger than a width of said substrate in the moving direction of the recording material.
