摘要： When a fixing device becomes uncontrollable and a large amount of electric power is continuously supplied to the heater, concentration of mechanical stress on a heater is suppressed, whereby shear fracture of the heater is prevented from occurring. A longitudinal region of the heater in which a heat generation resistive member is provided is supported by a heater support surface of a heater holder, and an opposed surface of the heater holder that is opposed to a longitudinal region of the heater in which the heat generation resistive member is not provided is designed not to be in contact with the heater.

摘要： An image heating apparatus for heating an image formed on a recording material, including a heater, a holder for holding the heater, a rotating member rotating around the holder and being flexible and having a metal layer, and a pressure roller forming a nip with the heater across the rotating member, wherein the rotating member moves detaching from the pressure roller just after passing through a downstream end portion of a surface of the heater opposed to the pressure roller. Thus, an uneven heating of a toner image can be prevented even in a case where the recording material becomes undulated after passing the nip portion.

摘要： A transfer plate which also serves as a sheet guide plate is pushed by a torsion spring. A minimum gap less than 0.2 mm between a guide surface of the transfer plate and the surface of a photoreceptor drum is maintained to be smaller than the thickness of a transfer sheet by a spacer member provided on the guide surface. When the sheet passes through the gap between the drum surface and the guide surface, the transfer plate is pushed down by the sheet and the sheet is pressed onto a toner image formed on the drum surface with an appropriate pressure by the pushing force of the torsion spring. At this time, a transfer voltage is applied to the transfer plate, so that the toner image on the drum surface is transferred to the sheet.
