Abstract
A film type fixing device includes a rotatable endless film; film position detecting device for detecting a position, in a direction perpendicular to a rotational direction, of the film; error detecting device for detecting error of a position of the film when the output of the film position detecting device is out of a predetermined range; and discriminating device for discriminating whether to back up error information or not on the basis of the output of the film position detecting device, when the error detecting device detects the error.
