Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member and a first heating stop device. The fixing belt is provided to be rotatable around a rotation axis. The pressuring member is configured to be rotatable and to come into pressure contact with the fixing belt so as to form a fixing nip. The heat source is arranged at an inner diameter side of the fixing belt, provided at a position displaced from the rotation axis and configured to heat the fixing belt. The pressing member is configured to press the fixing belt to a side of the pressuring member. The first heating stop device is configured to face an outer circumferential face of a closest part to the heat source of the fixing belt and to operate at a first operating temperature so as to stop the heat source from heating the fixing belt.

Abstract: A development device includes a development case, a first agitating/conveying member and a second agitating/conveying member. The first agitating/conveying member is arranged below the second agitating/conveying member to convey the developer in a first direction. The second agitating/conveying member conveys the developer in a second direction as an opposite direction to the first direction to supply the developer to the developer carrier. The development case includes a first conveyance chamber, a second conveyance chamber, a first communicating portion communicating end parts of the first conveyance chamber and second conveyance chamber in the first direction, and a second communicating portion communicating end parts of the first conveyance chamber and second conveyance chamber in the second direction. The developer carrier has a first ferromagnetic area having magnetic force stronger than another area of the developer carrier, in which the first ferromagnetic area corresponds to the first communicating portion.

Abstract: 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.
