摘要： A fixing device includes a heat source, a fixing roller, a pressure roller, an elastic layer, a pressing portion, a restricting portion and a driving unit. The fixing roller is heated by the heat source. The pressure roller is held in contact with the fixing roller and forms a fixing nip portion through which a sheet is to be passed. The elastic layer is formed on an inner layer of the fixing roller. The pressing portion presses one roller of the fixing roller and the pressure roller against the other roller while compressing the elastic layer. The restricting portion restricts a compression amount of the elastic layer lest the compression amount should exceed a preset compression amount when the pressing portion presses the roller. The driving unit drives and rotates one of the fixing roller and the pressure roller in a state where the compression amount is restricted.

摘要： A fixing device includes a heating body, a pressurizing body, a separation claw, and a supporting member. The heating body heats a medium where a toner image is formed while the heating body rotates around a shaft. The pressurizing body forms a nip with the heating body and applies pressure to the medium that passes through the nip while the pressurizing body rotates around a shaft. The separation claw includes a protrusion that contacts the medium after having passed through the nip and separates the medium from the heating body. The supporting member supports the separation claw in state of causing the separation claw into contact with the heating body. The supporting member supports the separation claw while the supporting member causes the separation claw to slide in a direction separating from the heating body when the medium is brought into contact with the protrusion to press the protrusion.

摘要： A fixing device includes a cylindrical rotatable heating member; a nip-forming member having a first surface and a second surface opposite from the first surface and contacting an inner surface of the rotatable heating member at the first surface; a supporting member having a supporting surface, contacting the second surface, for supporting the nip-forming member; and a pressing member for forming a nip in cooperation with the nip-forming member though the rotatable heating member. A recording material on which an image is formed is heated at the nip while being feed through the nip, and the image is fixed on the recording material. The supporting surface of the supporting member supports the second surface of the nip-forming member so that the nip-forming member is swingable relative to the supporting member about an axis substantially parallel with a rotational axis of the cylindrical rotatable heating member.

摘要： A fixing device includes a fixing rotary body and a pressing rotary body disposed opposite the fixing rotary body. A pivotable pressurization member contacts and presses the pressing rotary body against the fixing rotary body. A pressurization pivot is provided on the pressurization member. A depressurization member, pivotable about the pressurization pivot, causes the pressurization member to isolate the pressing rotary body from the fixing rotary body. A depressurization pivot is provided on the depressurization member. A lock is pivotable about the depressurization pivot and engageable with the pressurization pivot. A biasing member, anchored to the lock, exerts a resilient bias that allows the lock to cause the pressurization member to press the pressing rotary body against the fixing rotary body. A detent is situated in a pivotal trajectory of the lock to restrict pivot of the lock by contacting the lock.
