PROBLEM TO BE SOLVED: To obtain an image recording device capable of recording images of high quality with high precision by preventing trouble such as unevenness and fluctuations of an image due to uneven rotation of a polygon mirror. SOLUTION: An image exposure part B is equipped with a laser beam scanner 100 which deflects and outputs a laser light beam in a horizontal scanning direction by a polygon mirror and a conveyance unit 17 for vertical scanning which moves a recording medium 3 in a vertical scanning direction, which is such that the natural vibration frequency of a 1st stay supporting the laser beam scanner 100 at least nearby the polygon mirror is set to be≥5 Hz different from the natural vibration frequency of the polygon mirror 33 and its integral multiple.
