摘要： A pair of fixing section discharge rollers 24 is arranged on the downstream side, with respect to the paper conveying direction, of a fixing section 20 including a fixing roller 21 and a pressing roller 22. Near the fixing section 20, a openable section 40 is provided that makes externally accessible the paper conveying passage on the downstream side of the fixing section 20. The openable section 40 has the axis of its pivot portion 41 aligned with the axis of the pressing roller 22, and is rotatable about the pivot portion 41. The fixing section discharge rollers 24 are mounted on the openable section 40. If a paper jam occurs on the downstream side of the fixing section 20, when the openable section 40 is opened, a wide space is secured on the downstream side of the fixing section 20, and the paper P stuck in the conveying nip between the fixing section discharge rollers 24 is automatically brought outward.

摘要： A jam detecting device according to the present invention quickly outputs a jam detection signal when a part of a sheet is insufficiently conveyed during conveyance. A discharge detecting switch 55 is provided in the vicinity of discharge rollers 36. In addition, a plurality of (for example, three) pulse output units 230, 231 and 232 are provided in relation to the discharge detecting switch 55. Each of the pulse output units 230, 231 and 232 is so constructed as to output a pulse as the sheet is moved. In a jam judging circuit 235, when a signal of the discharge detecting switch 55 is on, a jam signal is outputted on the basis of the fact that no pulses are applied for not less than a predetermined time period from at least one of the pulse output units 230, 231 and 232. When a Jam occurs, therefore, the jam can be quickly detected. Consequently, the jam can be detected before a large sheet is crumpled or is tangled with a delivery roller in an image forming apparatus, whereby measures against the jam is easily taken.

摘要： A fixing unit includes: a casing; a heat roller that is rotatably supported and that supplies heat for fixing; and a tubular heater disposed in parallel in the heat roller along an axis thereof. The tubular heater includes a lead wire having a protruding end portion protruding outwardly from an axial end portion thereof. In addition, the tubular heater includes a flat terminal having one face thereof connected and fixed to the protruding end portion. Moreover, a fitting surface for fixing the flat terminal is formed in the casing. The fitting surface is arranged to be flat in an area excluding an area in which the protruding end portion is disposed and is provided with a clearance for storing the protruding end portion. Further, the flat terminal is fixed to the fitting surface with the one face of the flat terminal facing the fitting surface.
