摘要： PROBLEM TO BE SOLVED: To provide a fixing device in which the hardness decrease in a pressing member is suppressed, by regulating the amount of deformation of a pressing member.
SOLUTION: A guide member 74 is provided with a projection 74a, serving as a regulating means for regulating the amount of deformation of a pressing pad 110 during pressing. The projection 74a is integrally formed with the guide member 74 and projects toward a heating roll 70. The projection 74a is disposed in contact with the side face of a bearing 120 for the heat roll. Abutting of the projection 74a against the bearing 120 to the heat roll regulates the position of a block 112 to the heat roll 70, thus regulating the amount of deformation of the pressure pad 110.
