    摘要： A separation device separates a recording medium ejected from a fixing nip formed between a first rotator and a second rotator from the first rotator. The separation device includes a separator including a front end disposed opposite the fixing nip and the recording medium and a plurality of recesses disposed on the front end of the separator at least in a conveyance span on the separator where the recording medium is conveyed. The plurality of recesses includes a first recess extending in a first extension line that is oblique relative to a recording medium conveyance direction and a second recess adjacent to the first recess and extending in a second extension line that is oblique relative to the recording medium conveyance direction. The second extension line overlaps the first extension line in a direction perpendicular to the recording medium conveyance direction to define an overlap span.

    摘要： A separation device includes a separator that separates a recording medium from a rotator and a plurality of recesses disposed on a conveyance path side face of the separator over which the recording medium is conveyed in a recess span in a recording medium conveyance direction and at least in a conveyance span where the recording medium is conveyed. The plurality of recesses includes a first recess extending in a first extension line that is oblique relative to the recording medium conveyance direction and a second recess being adjacent to the first recess in a direction perpendicular to the recording medium conveyance direction. The second recess extends in a second extension line that is oblique relative to the recording medium conveyance direction and overlaps the first extension line of the first recess in the direction perpendicular to the recording medium conveyance direction to define an overlap span.

    摘要： A fixing device includes a pressing rotary body to press against a fixing rotary body. A pivotable pressure lever rotatably mounts the pressing rotary body. A pressurization cam assembly pivots the pressure lever to press the pressing rotary body against the fixing rotary body and release pressure between the pressing rotary body and the fixing rotary body. A pivotable cleaning unit includes a cleaning web separably contacting the pressing rotary body to clean the pressing rotary body, a pressure adjuster contacting the cleaning web to separably press the cleaning web against the pressing rotary body, a take-up reel to reel up the cleaning web, and a supply reel to reel out the cleaning web. A cleaning unit cam assembly contacts the cleaning unit to pivot the cleaning unit to press against and separate from the pressing rotary body.

    摘要： A fixing device fixes a toner image on a recording medium by heating the recording medium, with a heating area and a non-heating area selected in accordance with a magnetic flux and a repulsive magnetic flux. The fixing device includes a heat generating layer, an exciting coil, and a demagnetizing member. The heat generating layer generates heat. The exciting coil generates the magnetic flux, and thereby inductively heats the heat generating layer. The demagnetizing member faces the heat generating layer in the non-heating area. The demagnetizing member generates the repulsive magnetic flux against the magnetic flux generated by the exciting coil, and thereby demagnetizes the magnetic flux and suppresses the heating. Further, the demagnetizing member has a demagnetization effect different between at least a portion of the non-heating area adjacent to the heating area and the remaining portion of the non-heating area.

    摘要： A fixing device includes an exciting coil to generate a magnetic flux and a heat generation layer disposed opposite the exciting coil to generate heat by the magnetic flux from the exciting coil. A temperature sensitive magnetic body, disposed opposite the exciting coil via the heat generation layer, obtains and loses 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 made of a non-magnetic material having an electrical resistivity smaller than an electrical resistivity of the temperature sensitive magnetic body. The degausser is disposed opposite the exciting coil with an interval in a range of from about 4.2 mm to about 8.2 mm.
