Abstract
A fixing device includes a frame, a film, a component portion engaging with the frame, and a roller that forms a nip with the film. The component portion includes a supporting portion provided inside the film, and including a first opposing surface opposing an inner surface of the film, and a second opposing surface opposing the inner surface of the film. Each of the first opposing surface and the second opposing surface is a surface forming a substantially right angle with an engaging surface, which is a surface on which the component portion engages with the frame and on which the component portion opposes a flat surface portion of the frame. When the component portion is seen in the longitudinal direction of the film, a contour of the first opposing surface is greater than a contour of the second opposing surface.
