Abstract
A fixing device includes a film forming a cylinder, a heater, a thermometer, and a series of contact portions. The heater extends within the cylinder and includes a heating element that extends in a longitudinal direction along the cylinder. The thermometer detects a temperature of the cylinder. The plurality of contact portions contact an inner surface of the cylinder and are spaced apart from each other in the longitudinal direction. The contact portions include a first contact portion and a second contact portion. The first contact portion is longitudinally offset from the thermometer and has a first contact area with the cylinder. The second contact portion is longitudinally collocated with the thermometer and has a second contact area with the cylinder. The second contact area is smaller than the first contact area.
