Abstract: An image-forming apparatus contains a control portion that controls a cooling operation of the fixing portion. The control portion sets an image confirmable position in which an image formed on a long sheet is confirmable. When a print job on the long sheet finishes, the control portion starts the cooling operation of the fixing portion and controls the conveying portion to convey the long sheet until a rear end of a final image fixed by a fixing portion reaches the image confirmable position and finishes the cooling operation of the fixing portion until the rear end of the image fixed by the fixing portion reaches the image confirmable position. The control portion also sets the image confirmable position to be at an outermost circumference of rolled paper reeled by a reeling apparatus.

Abstract: An image forming apparatus includes the following. A conveying unit conveys a continuous sheet at least longer than a length of the apparatus itself. A first rotating member can be pressed to and separated from a second rotating member. The first rotating member can be rotated separated from the second rotating member. The continuous sheet can be stopped and held when the first rotating member is separated from the second rotating member. The image forming apparatus further includes a control unit. When the continuous sheet is stopped and held and the rotation of the first rotating member is started separated from the second rotating member, the control unit moves at least one of the first rotating member and the continuous sheet so that the continuous sheet is not in contact with the first rotating member, and then the control unit starts rotation of the first rotating member.

Abstract: There is described a fixing apparatus for fixing a toner image onto a recording material, which makes it possible not only to reduce the frictional resistance generated between a temperature sensor and a heating member, but also to prevent occurrences of abnormal sounds and breaking of the wire coupled to the temperature sensor, both caused by the direct contact between them. The fixing apparatus includes: a heating member provided with a surface layer, which is elastically deformable and includes the paper sheet passing area and the paper sheet non-passing area; a pressing member that press-contacts the heating member; and a temperature sensor that contacts the paper sheet non-passing area of the surface layer. A surface roughness Ra of the paper sheet non-passing area is set at such a value that is larger than that of a paper sheet passing area.

Abstract: The image forming apparatus cools the recording sheet with a cooling fan having an air duct with a first air-blowing outlet and a second air-blowing outlet for directing air from the cooling fan to an interior of the apparatus. An air flow changing member opens or closes the first and second air-blowing outlets, depending on the conveying path of the recording sheet.
