<p>PROBLEM TO BE SOLVED: To provide a fixation device capable of suppressing a heating unit from becoming immovable when a frame supporting a heating unit and a roller is deformed.SOLUTION: A fixation device comprises: a heating unit HU that forms a nip with a pressure roller 140 (roller); a first frame 400 that holds an end portion of the pressure roller 140 and holds the heating unit HU movably along a vertical direction; and a pressure mechanism 500 that energizes the heating unit HU toward the pressure roller 140. The first frame 400 includes a first regulation surface 445A and a second regulation surface 447A that hold a guided part of the heating unit HU in a cross direction and that regulate movement of the heating unit HU in the cross direction. In the first regulation surface 445A and the second regulation surface 447A, most distant end portions from the pressure roller 140 in the vertical direction face each other in the cross direction of the guided part of the heating unit HU.</p> |
