PROBLEM TO BE SOLVED: To solve the problem of a fixation device including a cylindrical film, a heater that contacts with the film, a heat conduction member that contacts with the heater, and a support member for supporting the heater with the heat conduction member interposed therebetween that the fixation device can suppress the temperature rise of a non-paper passing part, whereas the heat of the heater easily dissipates via the heat conduction member to prolong the warm-up time of the fixation device.SOLUTION: In a fixation device, when a portion of a heat conduction member corresponding to one end area and a portion of the heat conduction member corresponding to the other end area of the area of the heat conduction member in contact with a heater in a direction orthogonal to a generatrix direction of a film are defined as a first portion and a second portion, respectively, the first portion and the second portion of the heat conduction member are configured to be sandwiched between a support member and the heater; and a non-contact area where the support member and the heat conduction member are not in contact with each other is provided between the first portion and the second portion in the direction orthogonal to the generatrix direction.SELECTED DRAWING: Figure 7 |
