Abstract: A heating unit includes a rotating cylinder rotating about an axis parallel to a first direction. A heater having a width in a second direction is on the inner surface of the cylinder. A support member holds the heater fixed relative to the cylinder and includes an upstream member adjacent to the heater in the second direction and a downstream member adjacent to the heater in the second direction. The heating unit may include, in some examples, a stay supporting the support member, a guide member on the stay, and a temperature sensor to measure a temperature of an inner surface of the cylinder. In some examples, the support member may comprise a plurality of ribs.

Abstract: A pressure switching mechanism includes a rotatable support, a biasing member, and a switching rotation member. The rotatable support rotates around a first rotation shaft to support a contact member such that the contact member is movable in a direction toward or away from a contacted member. The biasing member has one end connected to a biased portion of the rotatable support, which is located on a side opposite the first rotation shaft with respect to a virtual line passing through a contact portion between the contact member and the contacted member, and applies a biasing force to the rotatable support. The switching rotation member is connected to another end of the biasing member opposite the one end of the biasing member, rotates around a second rotation shaft, and has a rotation operating end which is on a side opposite the second rotation shaft with respect to the virtual line.

Abstract: A fixing unit includes a plurality of first engagement portions which respectively engage with a plurality of first to-be-engaged portions to restrict a movement of a heating unit in a third direction intersecting with a first direction and a second direction. A fixed unit includes a second engagement portion which engages with a second to-be-engaged portion to restrict a movement of the heating unit in the first direction. The fixing unit includes a movable unit, a supporting member, and a reciprocating mechanism. The supporting member supports the movable unit such that the movable unit is movable along the first direction. The reciprocating mechanism causes the movable unit to reciprocate. The reciprocating mechanism causes the movable unit to reciprocate once every time a plurality of sheets pass between a first rotation member and a second rotation member in the fixing unit.

Abstract: A fixing apparatus includes a belt, a steering roller, a slide member, and a pressing rotation member that forms a nip portion by pressing the belt and is disposed to face the slide member. The belt applies heat to a recording material and has an inner circumferential surface that receives a lubricant applied onto the inner circumferential surface. The pressing rotation member fixes a toner image onto the recording material by applying heat and pressure to an unfixed toner image in the nip portion, in cooperation with the belt. An end portion of the belt on one end side in a belt width direction takes a position outside an end portion of the slide member on the one end side and a position inside the end portion of the slide member on the one end side while the steering roller is in operation.
