PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing a mirror from falling off due to the vibration and the drop of a device by surely pressing the mirror. SOLUTION: This image forming device is equipped with a mirror 7, mirror positioning parts positioned at the both ends of the mirror 7, mirror pressing springs (mirror pressing member) 21 being an elastic member having a V-shaped cross section for fixing the mirror 7 on the respective mirror positioning parts and generating elastic force for pressing the mirror 7 by an angle change on the V-shaped cross section and mirror supporting plates (supporting part) 13a and 13b supporting the spring 21. In such a case, a projection part is formed at the part of each of the plates 13a and 13b where the spring 21 is supported, a mirror pressing projection (pressing part) and a stopper part 23 pressing the end face of the mirror 7 in the longitudinal direction are formed at one end of the spring 21 and then, an engaging hole engaged with the projection part of each of the plates 13a and 13b and a rotation stop part 27 restricting the rotation in the direction where a U-shaped bent part 29 comes close to the mirror direction by making the end of the hole as a fulcrum are formed at the other end of the spring 21. |
