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 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 heater, a fixing rotator, a first temperature sensor, a second temperature sensor, a contact rotator, and circuitry. The fixing rotator has an outer circumferential surface having a first area and a second area. The first area contacts both a first sheet and a second sheet having a width narrower than the width of the first sheet. The second area contacts the first sheet but does not contact the second sheet. The first temperature sensor detects a first temperature of the first area. The second temperature sensor detects a second temperature of the second area. The contact rotator contacts both the first area and the second area and rotates at the one of at least two relative velocities with respect to the fixing rotator. The circuitry sets one of the at least two relative velocities based on the first temperature and the second temperature.

摘要： A fusing device includes a rotary fusing part; a heating unit heating the rotary fusing part; a rotary pressure part pressed against the rotary fusing part; nozzles jetting compressed air to paper being conveyed through a nip between the rotary fusing part and the rotary pressure part; and separating parts guiding the paper separated from the rotary fusing part. The nozzles and the separating parts are disposed downstream of the nip in a paper conveying direction so as not to contact the rotary fusing part and the rotary pressure part and are arranged alternately along the length direction of the nip that is orthogonal to the paper conveying direction. The separating parts protrude beyond the tips of the nozzles toward the nip.

摘要： A fixing device includes a fixing belt that is endless and rotatable in a rotation direction and a nip former stretching the fixing belt. A pressure rotator presses against the nip former via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium is conveyed. A separator is disposed downstream from the nip former in a recording medium conveyance direction and stretches the fixing belt. The separator is spaced apart from the pressure rotator via the fixing belt. A presser is interposed between an exit of the fixing nip and an upstream end of the separator in the rotation direction of the fixing belt. The presser comes into contact with an inner circumferential surface of the fixing belt to press the fixing belt against the pressure rotator.
