Abstract
A fixing device for fixing a toner image onto a recording medium, includes: a belt member rotatably provided; a heating section that heats the belt member; a pressurization member, placed so as to be pressed against the belt member, that forms a nip portion to allow the recording medium to pass through between the pressurization member and the belt member; and an uniforming section that uniforms a temperature distribution in a longitudinal direction of the pressurization member.

A fixing device for fixing a toner image onto a recording medium, the fixing device comprising:
- a belt member rotatably provided;
- a heating section that heats the belt member;
- a pressurization member, placed so as to be pressed against the belt member, that forms a nip portion to allow the recording medium to pass through between the pressurization member and the belt member;
- and
- an uniforming section that uniforms a temperature distribution in a longitudinal direction of the pressurization member.
A fixing device for fixing a toner image onto a recording medium, the fixing device comprising:
- a belt member rotatably provided;
- a heating section used that heats the belt member;
- a pressurization member, placed so as to be pressed against the belt member, that forms a nip portion to allow the recording medium to pass through between the pressurization member and the belt member;
- and
- a cooling member, placed at a distance from the pressurization member, that comes in contact with the pressurization member when the pressurization member thermally expands so as to cool the pressurization member.
An image forming apparatus comprising:
- an image forming device that forms a toner image on an image carrier;
- a transfer device that transfers the toner image onto a recording medium;
- and
- a fixing device that fixes the toner image onto the recording medium, the fixing device comprising:
