Abstract:
1. A fixing device comprising: a rotatable fixing belt; a first fixing roller in internal contact with an inner surface of the fixing belt, the first fixing roller comprising an outer diameter smaller than an inner diameter of the fixing belt; a second fixing roller in external contact with an outer surface of the fixing belt, the second fixing roller holding the fixing belt against the first fixing roller so as to define a fixing nip region between the first fixing roller and the second fixing roller; an end restriction member supporting ends of the fixing belt so as to restrict a rotation position of the fixing belt; and a support member disposed at a position in the end restriction member to pivotally support the first fixing roller, the position being shifted with respect to a center position of the end restriction member corresponding to a rotation center of the fixing belt, wherein 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 a rotation center of the first fixing roller and a rotation center of the second fixing roller to each other in a direction orthogonal to a rotation axis of the first fixing roller and a rotation axis of the second fixing roller.
