Claims
- 1. An image fixing elastic rotatable member, comprising:
- a core member; and
- a surface silicone rubber layer outside said core member;
- wherein said surface silicone rubber layer contains 0.003-0.3% by weight of a fluorine surface active agent.
- 2. A member according to claim 1, wherein said silicone rubber layer comprises 0.01-0.1% by weight of a fluorine surface active agent.
- 3. A member according to claim 1, wherein between said silicone rubber layer and said core member, there is provided an insulating rubber layer.
- 4. A member according to claim 3, wherein said insulating rubber layer is a porous layer.
- 5. A member according to claim 1, wherein said rotatable member forms a nip for feeding a material having the toner image.
- 6. A member according to claim 5, wherein said member is contactable to a material having the toner image at a surface not bearing the image.
- 7. A member according to claim 1, wherein a fluorine surface active agent is applied to said rotatable member.
- 8. A member according to claim 1, wherein said surface silicone rubber layer is hardened while containing said fluorine surface active agent.
- 9. An image fixing apparatus, comprising:
- a heating member;
- a back-up rotatable member, said back-up rotatable member having a core member and a surface silicone rubber layer outside said core member, wherein said surface silicone rubber layer contains 0.003-0.3% by weight of a fluorine surface active agent.
- 10. An apparatus according to claim 9, wherein said core member is electrically conductive, and said silicone rubber layer is electrically connected with said core member.
- 11. An apparatus according to claim 9, wherein said silicone rubber layer comprises 0.01-0.1% by weight of a fluorine surface active agent.
- 12. An apparatus according to claim 9, wherein between said silicone rubber layer and said core member, there is provided an insulating rubber layer.
- 13. An apparatus according to claim 12, wherein said insulating rubber layer is a porous layer.
- 14. An apparatus according to claim 9, wherein a fluorine surface active agent is applied to said rotatable member.
- 15. An apparatus according to claim 9, wherein said heating member is contactable to an unfixed toner image charged to a negative polarity on a recording material, and wherein said silicone rubber layer is a surface layer.
- 16. An apparatus according to claim 9, wherein said surface silicone rubber layer is hardened while containing said fluorine surface active agent.
