摘要： A fixing device includes: a fixing member that is rotatable and in an endless shape; a heat source that heats the fixing member; a nip forming member that is arranged inside the fixing member; and a pressurizing member that is pressurized to be in contact with the nip forming member through the fixing member, to form a fixing nip. The fixing device fixes an unfixed image on a recording medium by passing the recording medium that carries the unfixed image through the fixing nip. The nip forming member includes a base layer, and a high thermal-conductive layer that is arranged on a surface layer of the base layer on a fixing nip side, and that has higher thermal conductivity than the base layer, and in the high thermal-conductive layer, a low thermal-conductive portion is arranged near an end portion in an axial direction of the fixing member.

摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a heater that heats the fixing rotator. A nip formation pad is disposed opposite an inner circumferential surface of the fixing rotator. A pressure rotator presses against the nip formation pad via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. A low-friction member is sandwiched between the nip formation pad and the fixing rotator and bears a lubricant that flows in a flow direction. A thermal absorber is mounted on the inner circumferential surface of the fixing rotator. At least one irregular portion, mounted on the thermal absorber, blocks the lubricant flowing in the flow direction.

摘要： A fixing device includes a fixing rotary body rotatable in a given direction of rotation and a pressing rotary body pressed against the fixing rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed inside the fixing rotary body to heat the fixing rotary body. A reflector, disposed opposite an inner circumferential surface of the fixing rotary body via the heater, reflects light emitted from the heater onto the fixing rotary body. The reflector includes a movable portion movable relative to the heater to direct the light emitted from the heater onto a variable heating span of the fixing rotary body spanning in an axial direction thereof. The variable heating span varies depending on a width of the recording medium in the axial direction of the fixing rotary body.
