PROBLEM TO BE SOLVED: To provide a fixation device and the like capable of suppressing fixation failure that occurs when an annular belt becomes the unstable state before the belt reaches a fixation pressure-contact part formed by pressing the belt against the outer peripheral surface of a heating roller.SOLUTION: A fixation device comprises: a heating roller which rotates; an annular belt which is brought into contact with the outer peripheral surface of the heating roller to interlockingly rotate; and a pressure member provided with a pressing part which forms a fixation pressure-contact part by pressing the outer peripheral surface of the annular belt against a portion along the axial direction of the outer peripheral surface of the heating roller, an inlet guide part which is provided in a shape of protruding so as to approach the outer peripheral surface of the heating roller at the position on the upstream side in the rotation direction of the heating roller from the pressing part and guides the annular belt so as to come into contact with the portion along the axial direction of the outer peripheral surface of the heating roller before reaching the fixation pressure-contact part, and at least one intermediate guide part which is provided in a shape of protruding so as to approach the outer peripheral surface of the heating roller at the intermediate position between the pressing part and the inlet guide part and guides the annular belt so as to approach the portion along the axial direction of the outer peripheral surface of the heating roller to pass.SELECTED DRAWING: Figure 3 |
