Abstract: A fixing device includes a fixing member, a pressuring member and a temperature sensing part. The fixing member heated by a heat source contacts with a recording medium to heat a toner image on the recording medium. The pressuring member pressures the recording medium to the fixing member. The temperature sensing part in non-contact with the fixing member includes an infrared sensing element sensing infrared rays from the fixing member and a condensing member condensing the infrared rays to the infrared sensing element. Detection temperature of the fixing member is calculated with a sensing value by the infrared sensing element. The detection temperature or control temperature of the heat source is corrected with temperature deference between the infrared sensing element and the condensing member. Heating of the fixing member is controlled with the corrected detection temperature and the control temperature or the detection temperature and the corrected control temperature.

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

Abstract: A fixing device includes a housing, a belt member, a pressure roller, a nip forming member, and a pressing member. The belt member is constituted of a flexible tubular shape. The nip forming member is located at an inner peripheral portion of the belt member. The nip forming member has an opposed surface along an outer peripheral surface of the pressure roller. The nip forming member presses the belt member to the pressure roller. An end portion of the outer peripheral surface of the pressure roller is located inside with respect to an end portion of the belt member. The fixing device includes a pressing member located opposed to the pressure roller in the axial direction. The pressing member presses an outer peripheral surface of the end portion of the belt member in the axial direction to radially inward of the belt member.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source and a reflecting member. The fixing belt is arranged rotatably around a rotation axis. The reflecting member reflects the radiant heat radiated from the heat source. The fixing belt has a passing region and a non-passing region. Through the passing region, a recording medium passes. The non-passing region is arranged outside the passing region in a direction of the rotation axis. The reflecting member has a first reflecting part and a second reflecting part. The first reflecting part is arranged at an inner circumferential side of the passing region. The second reflecting part is arranged at an inner circumferential side of the non-passing region. Roughness of a face at the heat source side of the second reflecting part is larger than roughness of a face at the heat source side of the first reflecting part.
