PURPOSE:To obtain an image forming device constituted so that a reflecting mirror is prevented from being deformed and a precise image can be formed. CONSTITUTION:A reflecting mirror device 1 guiding the reflected light or the transmitted light of an original to an exposure part is constituted of an elastic member 2 elastically supporting one side surface of the reflecting mirror 4 and a projection 3 supporting the point of the central part P1, (P2 and P3) of the supporting position by the elastic member 2. Thus, since force for supporting and fixing the mirror 4 is balanced, the mirror 4 is not distorted or deformed. Besides, the reflected light is precisely reflected and exposure is precisely executed. |
