摘要： A separation device includes an endless belt, a rotary body, a separation supporter, and a transfer mechanism. The separation supporter presses against an inner circumferential surface of the endless belt downstream from an area of contact between the endless belt and the rotary body in a recording medium conveyance direction to curve the endless belt toward an outer circumferential surface side of the endless belt at a greater curvature than a curvature of the endless belt at the area of contact between the endless belt and the rotary body. The transfer mechanism switches the separation supporter between a first position and a second position farther from the area of contact between the endless belt and the rotary body than the first position.

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 fixing rotator and a slider that slides over the fixing rotator. A cam presses the slider against the fixing rotator. The cam includes a cam rear disposed opposite a rear end of the fixing rotator in an axial direction thereof and a cam front disposed opposite a front end of the fixing rotator in the axial direction thereof. A controller rotates the cam to a first slide position where the cam rear presses the slider against the fixing rotator, a second slide position where the cam rear and the cam front press the slider against the fixing rotator, a third slide position where the cam front presses the slider against the fixing rotator, and an isolation position where the cam rear and the cam front do not press the slider against the fixing rotator.

摘要： An image forming apparatus includes a fixing belt stretched across a first roller and a second roller including an elastic layer. A pressure rotator presses against the second roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A recording medium bearing a toner image is conveyed through the fixing nip. A clearance detector detects a clearance between the first roller and the second roller. A mover moves the pressure rotator with respect to the second roller in a pressing direction in which the pressure rotator presses against the second roller via the fixing belt and a separation direction in which the pressure rotator separates from the second roller. A controller controls an amount of movement of the pressure rotator moved by the mover toward the second roller based on the clearance detected by the clearance detector.

摘要： A fixing device, corresponding to a plurality of sheet passing widths, includes a rotating member configured to convey a recording medium, rise in temperature, and fix toner; temperature sensors configured to detect the surface temperature of the rotating member; heating members including at least one heat generating unit, provided inside the rotating member; and a control unit configured to control a heating state obtained by the heating members. The heat generating units are provided not to overlap each other in the direction of the sheet passing width orthogonal to the recording medium conveying direction. The temperature sensors are only placed at positions corresponding to the heat generating units used when printing on the recording medium having a minimum width. The control unit controls the heating state in accordance with the surface temperature, a sheet passing width, and an operational state of the rotating member that changes with time.
