A fixing device (13) includes a cylindrical heat roller (31), a heating element (32) provided inside the heat roller (31) and configured to apply heat to the heat roller (31), a pressure roller (33) configured to be pressed against the heat roller (31) to form, with the heat roller (31), a nip area (N) where a recording paper sheet (P) is to be nipped, and an auxiliary roller (34) provided inside the heat roller (31) and configured to be pressed toward the pressure roller (33) with a peripheral wall of the heat roller (31) in between. An outer peripheral surface of the auxiliary roller (34) pressed against an inner peripheral surface of the heat roller (31) is formed into an inverted crown shape so that an outside diameter of the auxiliary roller (34) gradually decreases from both axial ends of the auxiliary roller (34) toward an axial center thereof.
