PROBLEM TO BE SOLVED: To form an image having an excellent image quality by preventing vibration from a driving unit and a photoreceptor unit from being transmitted to an optical unit through a main body chassis. SOLUTION: The optical unit 7, the photoreceptor unit 3 and the driving unit 4 to drive a rotary driving system at the inside of the photoreceptive unit 3 are provided at the main body chassis 2 of an image forming device 1. A chassis 8 to which the optical unit 7 is attached is attached at the main body chassis 2 through a vibrationproof body, so that the vibration of the main body chassis 2 caused by the driving unit 4 and the photoreceptor unit 3 at the time of printing and actuating is hardly transmitted to the chassis 8 through the vibrationproof body. Also, the chassis 8 to which the optical unit 7 is attached is made of a vibrationproof material, so that the vibration of the main body chassis 2 is hardly transmitted to the optical unit 7.
