摘要： A sheet conveying device, which is included in a fixing device and an image forming apparatus, includes a sheet contacting body and a lateral relative position shifting body. The sheet contacting body is configured to contact a sheet to be conveyed. The lateral relative position shifting body is configured to shift a passing position of the sheet being conveyed toward the sheet contacting body, in a width direction perpendicular to a sheet conveying direction and a relative position to the sheet contacting body, each time the sheet is conveyed by a number of sheets based on a setting. The setting of the number of sheets varies based on information of the sheet.

摘要： A fixing device includes a tubular rotator and a first heater disposed inside the tubular rotator and extended in a longitudinal direction of the first heater. The first heater heats the tubular rotator. A second heater is disposed inside the tubular rotator and extended in a longitudinal direction of the second heater. The second heater heats the tubular rotator. A heating adjuster is interposed between the first heater and the second heater. The heating adjuster adjusts heat conduction from the first heater to the second heater. A joint combines the heating adjuster with the second heater.

摘要： A separation member that is used to separate a conveyance object from two rotation members, the conveyance object having been sent out from a nip that is formed by the two rotation members that are in contact with one another, the separation member includes a wavy part directed toward the nip and inclined from a normal to a center line of the two rotation members at a predetermined angle. The wavy part covers a contact zone where the conveyance object can come into contact with the separation member along a conveyance direction and along a width direction of the conveyance object, and the wavy part has a plurality of depressions parallel to each other and extending in a direction inclined from the conveyance direction and inclined from the width direction, at least two of the depressions overlapping along the conveyance direction.
