A fixing apparatus for use in an image forming apparatus such as a copying apparatus or a laser beam printer is disclosed. The fixing apparatus has a heater, a rotatable member having the heater therein, and a pressing member forming a nip by coming into contact with the rotatable member. The rotatable member is provided with a core and an elastic layer formed on the core, and the elastic layer has a JIS-A Standard rubber hardness not more than 5.degree..

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.
