Abstract
A fixing apparatus includes a film, a guide member, a stay member, a roller, and a restriction structure. The guide member is disposed in an inside space of the film, elongated in a generatrix direction of the film, and guides rotation of the film. The stay member reinforces the guide member, the film and a roller form a fixing nip portion between the film and the roller, and a recording medium having a toner image is heated to fix the toner image at the fixing nip portion while a sheet passes through the fixing nip portion. The roller is disposed in contact with an outside surface of the film. The restriction structure restricts movement of the guide member in a direction orthogonal to the generatrix direction of the film and also in a direction in which the stay member and the guide member are separated from each other.
