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 and a pressure rotator pressed against a nip formation pad via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed. The nip formation pad includes an increased thermal conduction portion having an increased thermal conductivity and a decreased thermal conduction portion having a decreased thermal conductivity and being inboard from the increased thermal conduction portion in the axial direction of the fixing rotator. The increased thermal conduction portion is disposed opposite a non-conveyance span of the fixing rotator where the recording medium is not conveyed and includes an inboard edge inboard from a lateral edge of the recording medium toward a center of the recording medium in the axial direction of the fixing rotator by a predetermined first distance.
