Claims
- 1. An image heating apparatus comprising:
- a heater which is stationary in use;
- a film slidable on said heater;
- a backup member cooperable with said heater to form a nip, with said film being interposed between said backup member and said heater, wherein an image carried on a recording material is heated through said film while in the nip by heat from said heater; and
- feeding interval controlling means for varying the recording material interval, wherein said control means expands the feeding interval each time the consecutive feeding of the recording material reaches a predetermined number as the recording materials are being consecutively fed.
- 2. An apparatus according to claim 1, wherein the number when the feeding interval is switched is different depending on the size of the recording material.
- 3. An apparatus according to claim 1, further comprising a temperature detecting element for detecting the temperature of the heater, said element detecting the heater temperature adjacent a recording material feeding position reference in a longitudinal direction of said heater.
- 4. An apparatus according to claim 3, further comprising power supply control means for maintaining a predetermined temperature of said heater.
- 5. An apparatus according to claim 1, wherein said apparatus thermally fixes an unfixed image carried on the recording material.
- 6. An image heating apparatus comprising:
- a heater which is stationary in use;
- a film slidable on said heater;
- a backup member cooperable with said heater to form a nip, with said film being interposed between said backup member and said heater, wherein an image carried on a recording material is heated through said film while in the nip by heat from said heater;
- electric power level detecting means for detecting electric power level supplied to said heater; and
- feeding interval controlling means for varying the recording material interval, wherein said feeding interval controlling means controls the feeding interval in response to an output of said electric power level detecting means as the recording materials are being consecutively fed.
- 7. An apparatus according to claim 6, wherein said apparatus thermally fixes an unfixed image carried on the recording material.
