摘要： A fixing device including a fixing unit that fixes a toner image on a recording material by application of heat and pressure, and a glossing unit that controls a gloss of the toner image fixed on the recording material. The glossing unit includes a heating roller, an endless belt stretched taut over multiple rollers including the heating roller, a pressing roller pressed against the heating roller with the endless belt therebetween to form a nip therebetween, and a separating member that separates the recording material from the endless belt downstream from the nip. The multiple rollers are positioned to maintain the recording material in contact with the endless belt for a predetermined distance downstream from the nip. The separating member is movable along the endless belt downstream from the nip, to control a length of contact between the recording material and the endless belt.

摘要： A glossing device includes a heater member, a stripper member, an endless rotary belt, a pressure member, and a belt cooler. The heater member is subjected to heating. The stripper member is disposed parallel to the heater member. The endless rotary belt is looped for rotation around the heater member and the stripper member in a longitudinal, conveyance direction of the belt. The pressure member is disposed opposite the heater member via the belt. The heater member and the pressure member press against each other via the belt to form a glossing nip therebetween. The recording medium after passage through the nip remains in contact with the belt as the belt moves from the heater member toward the stripper member, and separates from the belt as the belt passes around the stripper member. The belt cooler is disposed adjacent to the belt to cool the belt.

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 fixing device includes a belt forming a loop, a roller supporting an inner face of the belt, a pad, a slider, and a pressure rotator. The pad is inside the loop of the belt to press the inner face of the belt outward the belt. The slider is disposed between the belt and the pad to reduce friction between the belt and the pad. The pressure rotator presses the pad via the belt and the slider to form a fixing nip in which the belt and a recording medium are nipped between the pressure rotator and the slider to convey the belt and a recording medium in a conveyance direction. The pad has a recessed portion upstream from the fixing nip in the conveyance direction and extends in a longitudinal direction of the pad orthogonal to the conveyance direction.

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.
