摘要： A fixing device includes a fixing belt rotatably located around a rotation axis, a pressure member rotatably located, and a pressing member. The pressure member is brought into pressure contact with the fixing belt to form a fixing nip. The pressing member includes a pressing surface that presses the fixing belt toward a side of the pressure member. The pressing surface includes a plane surface portion extending along a conveyance direction of a recording medium, and a curved surface portion located at a downstream side of the plane surface portion in the conveyance direction of the recording medium. The curved surface portion is curved along an outer peripheral surface of the pressure member. The curved surface portion has a curvature radius larger than a curvature radius of the outer peripheral surface of the pressure member before a deformation in association with a formation of the fixing nip.

摘要： A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member, a heating stop device and a deformation preventing member. The deformation preventing member is configured to face an inner circumferential face of the fixing belt. In a state where the fixing belt is not broken in a circumferential direction, the fixing belt and the deformation preventing member are arranged at an interval, and when the fixing belt is broken in the circumferential direction, the fixing belt is deformed and comes into contact with the deformation preventing member so that the fixing belt is prevented from being deformed to a side far from the heating stop device.

摘要： A fixing device fixing an image on a recording medium includes a fixing belt rotatable around a first rotation axis, a pressuring member, a heat source body and a cover member. The pressuring member forms a nip part pressuring and making the recording medium pass through with the fixing belt. The heat source body is arranged inside the fixing belt and heats the fixing belt by emitting radiant heat. The cover member is arranged between the fixing belt and the heat source body and covers the heat source body. The nip part has a passing area where the recording medium passes through and a non-passing area outside the passing area in an axial direction. The cover member covers a part of the heat source body corresponding to the non-passing area and includes through holes formed so as to adjust surface temperature of the heat source body.

摘要： A developing device includes a housing containing a developer, a developer carrier, a developer conveying path, a developer conveying member, and a plurality of paddle members. The developer conveying path includes a first conveying path and a second conveying path. The developer conveying member is disposed in the second conveying path and includes a rotating shaft and spiral blades formed around the rotating shaft. The developer conveying member is rotationally driven to convey the developer in the second direction and feeds the developer to the developer carrier. The plurality of paddle members project in a radial direction from the rotating shaft of the developer conveying member at one circumferential position on the rotating shaft. The plurality of paddle members is contiguously arranged in the axial direction of the rotating shaft to connect the spiral blades adjacent to each other in the axial direction.

摘要： A fixing device includes a heating body, a pressuring body, a temperature detecting part, a first frame supporting the heating body, a second frame supporting the pressuring body and a moving mechanism. The temperature detecting part has a detecting element detecting an infrared ray radiated from the heating body and detects temperature of the heating body by the detecting element. The first frame includes a heat interrupting member covering the heating body between the heating body and the temperature detecting part. The moving mechanism moves the first frame in an approaching direction or a separating direction from the second frame to establish the heating body and the pressuring body in a pressurization state or a depressurization state. The heat interrupting member includes an aperture elongated in a movement direction of the first frame to pass the infrared ray radiated from the heating body to the detecting element through the aperture.
