First and second frame parts 400a and 400b support a belt guide 431 by interposing the belt guide 431 therebetween. The first frame part 400a is disposed at a downstream side of in rotation direction of a pressure roller 44 than the second frame part 400b when seeing it in a direction parallel to a rotation axis of the pressure roller 44. A convex-shaped first belt guide support part 401a for supporting the belt guide 431 is provided on a surface of the first frame part 400a, which faces the second frame part 400b. A convex-shaped second belt guide support part 401b for supporting the belt guide 431 is provided on a surface of the second frame part 400b, which faces the first frame part 400a, at a position, which is more separated from the pressure roller 44 than the first belt guide support part 401a. |

1. A fixing device comprising:
a pressure roller; an endless-shaped fixing belt having flexibility; a pressure-contacting member to pressure-contact the pressure roller by interposing the fixing belt therebetween; a belt guide to rotatably support the fixing belt and to simultaneously support the pressure-contacting member; and first and second frames to support the belt guide by interposing the belt guide therebetween, wherein the first and second frames slidably support the belt guide in a direction where the pressure-contacting member pressure-contacts the pressure roller, wherein the first frame is disposed at a downstream side of the second frame in a rotation direction of the pressure roller when viewing the configuration of the first frame and the second frame in a direction parallel to a rotation axis of the pressure roller, wherein a convex-shaped first belt guide support part to support the belt guide is provided on a surface of the first frame, which faces the second frame, and wherein a convex-shaped second belt guide support part to support the belt guide is provided on a surface of the second frame, which faces the first frame, at a position, which is more separated from the pressure roller than the first belt guide support part. |
