Fixing device with means for limiting a distance between heating and pressing member |
摘要 |
In a fixing device, a limitation member for preventing the center distance between a heating member and a shaft of a pressing roller from being reduced does not limit the center distance in an initial state of the device, and prevents a further decrease in the distance when the distance is reduced. It is thereby possible to suppress an increase in the width of a nip portion provided between the heating member and the pressing roller, and to prevent a failure in fixing.
