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 fixing device includes a heater, a fixing rotator, a pressure rotator, a slider, and a controller. The fixing rotator is heated by the heater. The pressure rotator presses at least a portion of the fixing rotator and forms a nip between the pressure rotator and the fixing rotator. The fixing rotator fixes an unfixed toner image on a recording material in the nip. The slider slides over a surface of the fixing rotator. The controller causes the slider to perform a first sliding operation for a predetermined time after a predetermined condition is satisfied. The controller causes the slider to perform a second sliding operation for a time equal to or less than the predetermined time at earlier timing than when the predetermined condition is satisfied, in addition to the first sliding operation.

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.

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.
