摘要： A heating device includes a pair of rotators, a heater, a temperature sensor, a conductor, a conductor support, and a component supporting the conductor. The pair of rotators is in contact with each other to form a nip through which a sheet passes. The heater heats at least one of the pair of rotators. The temperature sensor detects a temperature of the heater. The conductor has flexibility and is coupled to the temperature sensor. The conductor support supports the conductor such that a distance from the conductor to at least one position of the heater outside a predetermined region of the heater in a width direction of the sheet is larger than a distance from the conductor to a position of the heater inside the predetermined region in the width direction. The component has a first side facing the heater and a second side opposite the first side.

摘要： 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.

摘要： A heating device includes a first rotator and a second rotator that contacts the first rotator to form a nip between the first rotator and the second rotator. A heater heats at least one of the first rotator or the second rotator. A first support frame supports one lateral end of the first rotator and the second rotator in a longitudinal direction of the first rotator and the second rotator. A second support frame supports another lateral end of the first rotator and the second rotator in the longitudinal direction of the first rotator and the second rotator. An incompatible member is mounted on the first support frame.

摘要： A fixing device includes a belt and a holder that holds a heater. A conductive member contacts an inner face of the belt and pivots. The conductive member includes one end portion in a rotation direction of the belt and an opposed portion that abuts on the one end portion. A support supports the holder and presses the conductive member against the holder. The holder includes a holding portion that holds the one end portion of the conductive member, a pivot restrictor that restricts pivoting of the conductive member about the one end portion, and a mount face from which the pivot restrictor projects in a projecting direction. The pivot restrictor projects farther than the opposed portion of the conductive member in the projecting direction of the pivot restrictor in a state in which the support does not press the conductive member against the holder.

摘要： A heating device includes a rotator, a heater, lubricant, a rotator support, and a cover. The rotator has an internal space inside a loop of the rotator. The rotator has an internal space inside a loop of the rotator. The heater heats the rotator. The lubricant is applied to an inner circumferential surface of the rotator. The rotator support supports an end of the rotator in a longitudinal direction of the rotator. The rotator support has a first opening communicating with the internal space of the rotator and penetrating through the rotator support to extend in the longitudinal direction. The cover covers the first opening and has a second opening communicating between the internal space of the rotator and an external space outside the cover.

摘要： An image forming apparatus includes a cooler and a heater. The heater includes a heat generation unit, which includes resistive heat generators arranged in a longitudinal direction of the heater, a first electrode, a second electrode, a first conductor that connects the resistive heat generators in parallel with each other to the first electrode, and a second conductor that connects the resistive heat generators in parallel with each other to the second electrode. The first and second conductors are connected to at least one of the resistive heat generators on a first longitudinal end side of the heater from a center of the resistive heat generator in the longitudinal direction of the heater. A cooling ability of the cooler to a second longitudinal end side of the heater opposite the first longitudinal end side of the heater is greater than that to the first longitudinal end side of the heater.
