摘要：
A fixing device includes an endless belt and a belt holder contacting and rotatably supporting each lateral end of the endless belt in an axial direction thereof. A first protection ring and a second protection ring are interposed between the endless belt and the belt holder in the axial direction of the endless belt and rotatable in accordance with rotation of the endless belt to protect each lateral end of the endless belt as the endless belt is skewed in the axial direction thereof and brought into contact with the first protection ring. A friction coefficient between the first protection ring and the second protection ring is smaller than a friction coefficient between the first protection ring and the endless belt.
