PROBLEM TO BE SOLVED: To prevent deterioration in quality of scanning image by preventing vibration due to a rotation of a cooling fan from making an optical part of an image scanning part or an image writing part vibrate sympathetically. SOLUTION: Related to an image formation device that comprises an image scanning part 1 and has a cooling fan 52 in the device, vibration frequency generated by the rotation of the cooling fan 52 is set apart from the characteristic frequency of the optical part in the image scanning part 1 and an image writing part 2 and the value that is integral multiple thereof, by a specified value. |
