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 fixing rotator, a pressing rotator, an oil applicator, a first adjuster, a surface modifier, a second adjuster, and a processor. The fixing rotator contacts a recording medium bearing a toner image. The pressing rotator forms a fixing nip with the fixing rotator. The oil applicator is pressed against at least one of applied members of the fixing rotator and pressing rotator. The first adjuster adjusts contact/separation of the oil applicator with respect to the applied member. The surface modifier contacts the fixing rotator to modify a surface thereof. The second adjuster adjusts contact/separation of the surface modifier with respect to the fixing rotator. The processor allows the surface modifier to modify the fixing rotator surface after the oil applicator contacts the applied member, and the oil applicator to separate from the applied member after the surface modifier is separated from the fixing rotator.

摘要： An image forming apparatus includes a rotary fixing member cleaner that includes a freely rotatable rotary unwinding member, around which a cleaning web winds, a rotary winding member to wind the cleaning web thereon from one end thereof, and a load applicator to apply a load to the cleaning web unwound from the rotary unwinding member. The rotary fixing member cleaner removes any unnecessary substance adhering to an outer circumferential surface of the rotary fixing member therefrom by unwinding and moving the cleaning web from the rotary unwinding member in an opposite direction to a direction of movement of the outer circumferential surface of the rotary fixing member at a contacting point at which the cleaning web contacts the outer circumferential surface of the rotary fixing member. The load applicator presses against the cleaning web winding around the rotary unwinding member at a prescribed angular contact position.

摘要： A sheet processing device includes a conveyance member, an elastic plate member, a first conveyance path, and a second conveyance path. The conveyance member conveys a sheet of recording media with the sheet attached thereon and has a circumferential portion to separate the sheet from the conveyance member by a curvature of the conveyance member. The first conveyance path is formed by the conveyance member. The second conveyance path is disposed downstream from the first conveyance path and includes a reversal conveyance path to reverse the sheet. A face continuous to a front edge of the elastic plate member, except for the front edge, is positioned in an attachment weakened area of the circumferential portion of the conveyance member in which an attachment force of the sheet on the circumferential portion is weakened by separation of the sheet from the conveyance member by the curvature.
