摘要： A fixing device includes a heat generating member, an endless belt, and a heat conductive member that contacts the heat generating member in a first region. A positioning portion is provided at an end portion of the heat conductive member, so as to extend in a direction in which the positioning portion is spaced apart from the heat generating member. A supporting member is provided with a first opening at a position corresponding to a second region of the heat generating member, and supports the heat generating member via the heat conductive member. An electrical power shut-off member, located in the first opening of the supporting member, shuts off electrical power supplied to the heat generating member. The positioning portion is inserted into the first opening of the supporting member to prevent movement of the heat conductive member.

摘要： A fixing member is provided which is excellent in durability and hardly undergoes the peeling of the surface layer even when used in a heating apparatus over a long term. The fixing member is an electrophotographic fixing member including a substrate, an elastic layer, an intermediate layer and a fluororesin-containing surface layer. The elastic layer includes a silicone rubber and sodium ions, and the intermediate layer includes an amino group-containing polysiloxane. The surface layer is formed by forming, on the intermediate layer, a primer layer including a copolymer, to which a phosphate group is bound, of tetrafluoroethylene and perfluoro(alkyl vinyl ether), forming, on the primer layer, a coating film including the copolymer of tetrafluoroethylene and perfluoro(alkyl vinyl ether) or a coating film including a copolymer of tetrafluoroethylene and hexafluoropropylene, and melting the copolymer in the primer layer and the copolymer in the coating layer.

摘要： A heater includes a substrate, a first heating element and a second heating element disposed on a first surface of the substrate, a temperature detection element, and a conductor. The temperature detection element is disposed on a second surface of the substrate opposite the first surface of the substrate. The conductor is disposed on the second surface and connected to the temperature detection element. The first heating element has a first distance from the temperature detection element in a lateral direction of the substrate orthogonal to a longitudinal direction of the substrate, and the second heating element has a second distance that is greater than the first distance from the temperature detection element in the lateral direction. As viewed in a thickness direction of the substrate orthogonal to the lateral direction and the longitudinal direction of the substrate, the conductor overlaps the first heating element and the second heating element.

摘要： A fixing device includes a first rotatable member, a second rotatable member, a heat generating member that heats the first rotatable member, and a temperature detecting member that detects a temperature of the heat generating member. A motor drives one of the first rotatable member and the second rotatable member. In addition, a controller controls the fixing device by causing the motor to rotate in a state in which a predetermined amount of electrical power is supplied to the heat generating member, and then, supply of the electrical power to the heat generating member is stopped. On the basis of a temperature lowering rate of a detected temperature of the temperature detecting member during rotation of said motor, the controller detects, after stopping supply of the electrical power to the heat generating member, a rotational state of the one of the first rotatable member and the second rotatable member.
