摘要: A fixing device includes fixing rotator, a heater to heat the fixing rotator, a pressure rotator disposed opposite an outer circumferential surface of the fixing rotator, a pressure pad disposed opposite an inner circumferential surface of the fixing rotator, a support to support the pressure pad, and a thermal conduction aid to conduct heat in an axial direction of the fixing rotator. The pressure pad presses against the pressure rotator via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The pressure pad includes a nip-side face disposed opposite the inner circumferential surface of the fixing rotator. The thermal conduction aid covers the nip-side face of the pressure pad. The nip-side face of the pressure pad includes at least one mouth therein defining a non-contact area in which the pressure pad does not contact the thermal conduction aid.

摘要: A fixing device includes a heat generator being disposed inside a loop formed by a rotator and including a heat generating portion to radiate radiant heat. A reflector is disposed inside the loop formed by the rotator and includes a reflection face to reflect the radiant heat radiated from the heat generator toward the rotator. A support supports the reflector. A holder holds each lateral end of the support in a longitudinal direction of the support, which is perpendicular to the rotation direction of the rotator. A fastener attaches the reflector to the support at an attachment position disposed at each lateral end of the reflector in a longitudinal direction of the reflector. The attachment position is disposed outboard from a lateral edge of the heat generating portion of the heat generator and disposed inboard from the holder in the longitudinal direction of the reflector.

摘要: A nip forming member includes a base material and a thermal conductive member that overlaps the base material and has a higher thermal conductivity than a thermal conductivity of the base material. The base material has protrusions projecting to one side or another side in a short direction on a part of a longitudinal direction on both sides in the short direction. The thermal conductive member has fitting holes into which the protrusions are fitted in both sides in the short direction.
