Abstract: A fixing device includes a rotatable fixing belt contacting an inner surface of the fixing belt. A second fixing roller contacts an outer surface of the fixing belt to hold the fixing belt against the first fixing roller to define a fixing nip region. An end restriction member supports ends of the fixing belt to restrict its rotation position. A support member is disposed at a position in the end restriction member to pivotally support the first fixing roller. The position is shifted with respect to a center position of the end restriction member corresponding to a rotation center of the fixing belt. The rotation center of the fixing belt is shifted toward a recording-paper conveyance direction of the fixing nip region with respect to a straight line connecting rotation centers of the first and second fixing rollers in a direction orthogonal to their rotation axes.
