Claims
- 1. An image fixing apparatus, comprising:
- a heater having at least generating resistor for generating heat upon electric power supply and a protection layer for protecting said heat generating resistor; and
- a resin film movable with one surface in contact with said protection layer and the other surface in contact with a recording material having a visualized image, said film comprising a heat resistive resin base layer contactable to said protection layer and a parting layer thereon contactable to said recording material;
- wherein said base and parting layer comprise filler materials, and the filler material in said base layer has a higher resistivity than the filler material in said parting layer.
- 2. An apparatus according to claim 1, wherein a content of the filler material in the base layer is 0.1-30% by weight.
- 3. An apparatus according to claim 2, wherein the content of the filler material in the base layer is 1-30% by weight.
- 4. An apparatus according to claim 1, wherein the filler material contained in the base layer has a thermal conductivity not less than 2.0.times.10.sup.-3 cal/cm.multidot.sec.multidot..degree. C.
- 5. An apparatus according to claim 1, wherein said heater is stationary in use, and wherein the heat resistive resin base layer is in sliding contact with said heater.
- 6. An apparatus according to claim 5, wherein said heat generating resistor extends in a direction perpendicular to a movement direction of said film.
- 7. An apparatus according to claim 5, wherein there is no air layer between the heat generating resistor and the visualized image.
- 8. An apparatus according to claim 1, wherein the filler material in said base layer is electrically insulative, and the filler material in said parting layer is electrically conductive.
- 9. An apparatus according to claim 1, wherein the filler material in said base layer is inorganic material.
- 10. An apparatus according to claim 1, wherein said filler material in the base layer is in the form of whiskers.
- 11. An apparatus according to claim 1, wherein said filler material in the parting layer is in the form of whiskers.
- 12. An apparatus according to claim 1, wherein said heater has a protection layer on said heat generating resistor, and wherein said base layer is in contact with said protection layer.
