摘要： A fixing device includes a fixing rotator to fix an image on a recording medium, a pressure rotator to press against an outer circumferential surface of the fixing rotator, a nip formation pad disposed inside the fixing rotator and opposite the pressure rotator to form an area of contact between the fixing rotator and the pressure rotator, and a slide member disposed between the fixing rotator and the nip formation pad and applied with lubricant to slide the fixing rotator in a sliding direction. The slide member includes first strands disposed parallel to the sliding direction and second strands disposed perpendicular to the sliding direction and interwoven with the first strands. The first strands are woven over the second strands longer than the second strands woven over the first strands.

摘要： A fixing device includes a heater, a fixing rotator, a pressure rotator to press against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed, a moving device to move the pressure rotator in directions in which the pressure rotator comes into contact with and separates from the fixing rotator, a thermal expansion amount predictor to predict an amount of thermal expansion of the fixing rotator while the recording medium is conveyed, and a nip width adjuster to control a moving distance of the pressure rotator moved by the moving device toward the fixing rotator, depending on the amount of thermal expansion of the fixing rotator predicted by the thermal expansion amount predictor, so as to adjust a width of the fixing nip to maintain a substantially constant width of the fixing nip.

摘要： A fixing device includes a fixing rotator, a heat source, a pressing member, a nip formation member, a reflector, and a support. The heat source is configured to heat the fixing rotator. The pressing member is configured to form a nip with the fixing rotator. The nip formation member is disposed inside a loop of the fixing rotator and opposed to the pressing member to form the nip between the fixing rotator and the pressing member. The reflector is configured to reflect heat from the heat source. The support is configured to secure the reflector. The support is in contact with the reflector at at least one end portion in a longitudinal direction of the support.

摘要： A fixing device includes an exciting coil and a heat generator disposed opposite the exciting coil. The heat generator includes a heat generation layer disposed opposite the exciting coil to generate heat by a magnetic flux from the exciting coil and a temperature sensitive magnetic body disposed opposite the exciting coil via the heat generation layer to obtain and lose magnetism at a temperature defined by a Curie temperature by composition adjustment to selectively create a heating region and a non-heating region of the heat generation layer. A degausser is disposed opposite the heat generator and made of a non-magnetic material having an electrical resistivity smaller than that of the temperature sensitive magnetic body. A holder contacting and supporting the degausser is disposed inboard from a lateral edge of the degausser and outboard from a lateral end of the exciting coil in a longitudinal direction of the degausser.

An air flow path is formed by a surface of the latent image carrying body and a surface of the duct wall, between the upstream suction port and the downstream suction port. A gap of the air flow path is wider at the downstream side than at the upstream side with respect to the rotational direction of the latent image carrying body.
