Abstract
A fixing device includes a fixing belt, a nip forming member, a pressing roller, a housing, a planer heater, a pair of belt holders, and a pressing mechanism. The pressing mechanism has a pair of pressing springs that urge the pair of belt holders toward the pressing roller, and a pair of pressing plates that are arranged opposite the pair of belt holders and swing toward or away from the belt holder. The pressing mechanism swings the pressing plate to adjust the urging force of the pressing spring. The pressing springs are compression coil springs and their diameter is larger than the width-direction length of the planer heater, which is the same as the rotation direction of the fixing belt, and the central axis of the pressing spring coincides with a straight line passing through the rotation centers of the fixing belt and the pressing roller.
