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 presser is disposed downstream from an exit of the fixing nip in a recording medium conveyance direction. The presser brings the fixing belt into contact with the pressure rotator. A gap retainer contacts the nip former and is coupled to the presser to retain isolation of the presser from the nip former.

摘要： A fixing device includes a heater, a fixing rotator, a pressure rotator, a slider, and a controller. The fixing rotator is heated by the heater. The pressure rotator presses at least a portion of the fixing rotator and forms a nip between the pressure rotator and the fixing rotator. The fixing rotator fixes an unfixed toner image on a recording material in the nip. The slider slides over a surface of the fixing rotator. The controller causes the slider to perform a first sliding operation for a predetermined time after a predetermined condition is satisfied. The controller causes the slider to perform a second sliding operation for a time equal to or less than the predetermined time at earlier timing than when the predetermined condition is satisfied, in addition to the first sliding operation.

摘要： A sheet separating device is attached to a fixing device. The fixing device includes: a fixing member that is a rotary body having a heating unit; and a pressing member that is pressed against and is brought into contact with the fixing member. The fixing device conveys a sheet material that carries unfixed toner thereon through a nip section formed by the fixing member and the pressing member so as to fix the unfixed toner image to the sheet material. The sheet separating device includes: at least one nozzle member that discharges compressed gas from the direction of a nip outlet toward the nip section along the fixing member. The nozzle member is rotatably supported by a shaft member that is provided parallel to the fixing member and includes a gas flow passage through which compressed gas is supplied to the nozzle member.

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 heater, a rotary fixing member, and a rotary pressing member pressing against the rotary fixing member to form a nip therebetween through which a recording medium bearing a toner image passes to fix the toner image thereon. The fixing device includes an air supply tube disposed downstream from the nip in the direction of conveyance of the recording medium and connected to an air source of an image forming apparatus, to supply compressed air to a plurality of nozzles disposed on the air supply tube along a long axis of the nip perpendicular to the direction of conveyance and inject pulsed compressed air against the recording medium passing through the nip. The air supply tube includes an exhaust opening disposed at an extreme upstream end of the flow of the compressed air outside the recording medium passing area near the air source.
