PROBLEM TO BE SOLVED: To provide a fixing device that suppresses failure in collection of light compared with a fixing device that causes light to enter the outer peripheral surface of a portion opposite to an apex included in a curved surface that is formed at an end of a lens on a belt and collects the light at the other end of the lens.SOLUTION: A fixing device 20 includes: an endless belt 52 that rotates on a shaft and transmits light; a lens 54 that has a curved surface 54A having an apex TS1 closest to the inner peripheral surface of the belt 52 formed on one end and collects light entered the curved surface 54A on a developer image G when viewed from a shaft direction; and a light source 66 that causes the light collected on the developer image G to enter a portion other than a portion opposite to the apex TS1 on the belt 52 and has a smaller amplitude than the amplitude of the portion opposite to the apex TS1 on the belt 52.SELECTED DRAWING: Figure 2 |
