    摘要： A fixing unit includes an endless belt unit accommodating a heat source, a pressure roller to rotate in contact with the fixing belt unit forming a pressure border therebetween, and a heat transfer member heated by the heat source to heat the fixing belt unit. The heat transfer member is secured inside an inner circumferential surface of the fixing belt unit and supports the fixing belt unit. A fixed member is secured inside the inner circumferential surface of the fixing belt unit and is pressed against the pressure roller via the fixing belt unit. The heat transfer member has at least one convex portion partially formed in an outer circumferential surface of the heat transfer member in a rotational direction of the fixing belt unit and a longitudinal direction of the heat transfer member to narrow a gap formed between the heat transfer member and the fixing belt unit.

    摘要： A fixing device fixes a toner image on a recording medium transported to a fixing nip by applying pressure and heat to the recording medium. The fixing device includes an endless belt formed into a loop with both ends bonded together, the belt accommodating a heat source inside thereof, a pressing roller rotating in contact with the endless belt forming the fixing nip between the endless belt and the pressing roller, and a fixed member provided inside a loop of the endless belt to press the endless belt against a pressing roller. A reinforcing member is bonded to the fixed member inside the loop of the endless belt to reinforce the fixed member. A reflector is provided to reflect light emitted from the heat source toward the inner circumferential surface of the endless belt. The reflector is held on the reinforcing member by either plastically or elastically deforming by itself.

    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.
