Abstract
An image heating apparatus in an image forming apparatus includes a temperature detecting element, an elastic member for pressuring the temperature detecting element and a film for covering the temperature detecting element. Conventionally, since the elastic member whose width is smaller than the width of the film completely covers the temperature detecting element and the elastic member, it has been necessary to prevent the film from interfering with and riding onto a heater holder equipped beside those parts. For improvement of the above problem, the elastic member whose width is larger than the width of the film is provided to be able to pressure an edge of the film.
Claims16
An image heating apparatus comprising:
- a heater;
- and
- temperature detecting means for detecting a temperature of said heater, said temperature detecting means having a temperature detecting element, an elastic member for holding said element, and a film for covering said elastic member,
- wherein the width of said film is smaller than the width of said elastic member.
An image heating apparatus comprising:
- a heater;
- a holder for holding said heater;
- and
- temperature detecting means for detecting a temperature of said heater, said temperature detecting means having a temperature detecting element and a supporting member for holding said element;
- wherein said temperature detecting element detects the temperature of said heater through a hole formed in said holder, and said holder has positioning portions for positioning said supporting member at the right and left of the hole of said holder.
