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 member; an opposing member that provides a fixing nip with the fixing member; a heating unit that heats the fixing member; a heating area changing member that moves to change a heating area of the fixing member heated by the heating unit; and a position detection sensor that detects a position of the heating area changing member. The fixing device controls a stop position of the heating area changing member based on detection by the position detection sensor. The single position detection sensor detects the position of the heating area changing member both when the heating area changing member is moving from a preset reference position to an arbitrary position and when the heating area changing member is moving back from an arbitrary position to the reference position.

摘要： A paper conveying device includes a conveying guide, a bearing, a conveying-guide facing surface, and a separation restrictor. The conveying guide includes a conveyance surface for conveying paper and a pivot shaft and is swingable about the pivot shaft. The bearing includes a support surface facing at least an upper semiperimeter of the pivot shaft. The conveying-guide facing surface is provided to face an end of the conveying guide when the conveying guide swings. The end is opposite to the conveyance surface. The separation restrictor is provided to the conveying guide to restrict separation of the pivot shaft from the bearing at least in a given swing range of the conveying guide by contacting the conveying-guide facing surface.
