A method and a device for exposing an image on an exposure plane by moving a plurality of exposure heads relatively to a the exposure plane in a predetermined scanning direction in which the image is exposed appropriately without causing any deviation of images between the exposure heads. Reference points (rp21, rp12) for respective exposure heads (3021, 3012) are formed on the exposure plane by using reference micromirrors (r21, r12) preset for the respective exposure heads (3021, 3012), and exposure timing by the respective exposure heads (2021, 3012) is controlled such that the reference points (rp21, rp12) for the respective exposure heads (3021, 3012) are arranged on a reference line (RL). |
