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 heater, a rotator, and a pressure rotator. The heater includes resistive heat generators forming a heat generation area and has a separation area formed by the resistive heat generators. The pressure rotator includes a first region and a second region. The first region faces the heater in a range of 20 mm from a center position of the heat generation area toward an end thereof in the arrangement direction. The second region faces the heater in at least a part of a range of 30 mm from a center position of the separation area toward the center position of the heat generation area. An outer diameter of the pressure rotator increases from the center toward the end. The outer diameter of the second region increases at an increasing rate larger than an increasing rate of the outer diameter of the first region.

摘要： A nip former includes a base, an enhanced thermal conductor including an insertion hole, and a securing member including an inserting portion to be inserted into the insertion hole to attach the securing member to the enhanced thermal conductor such that the enhanced thermal conductor and the securing member sandwich the base. The inserting portion has a width that is smaller than a width of the insertion hole in a pressurization direction of an opposed rotator that presses against the nip former via a belt. The inserting portion does not contact an upstream wall and a downstream wall of the insertion hole in the pressurization direction of the opposed rotator and a direction opposite the pressurization direction of the opposed rotator in a state in which the securing member is secured to the base and the opposed rotator presses against the enhanced thermal conductor via the belt.

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 heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.
