PROBLEM TO BE SOLVED: To prevent a sheet from entering between a temperature detection sensor and a heating roller.SOLUTION: A fixation device 8 is configured to fix a toner image on a sheet at a nip NP while conveying a sheet on which a toner image is formed. The nip NP is formed by pressuring a heating roller 8a heated by a halogen heater and a pressure roller 8b. The fixation device 8 includes: a temperature detection sensor 81 configured to make contact with part of a sheet conveyance outside region F of the heating roller 8a so as to detect a temperature of the heating roller 8a; and an entry inhibition guide 83 arranged at the sheet conveyance outside region F between a sheet conveyance region E and the temperature detection sensor 81 and at an upstream side of a sheet conveyance direction A of the heating roller 8a and configured to inhibit a sheet from entering between the heating roller 8a and the temperature detection sensor. |
