An image exposing apparatus, in which a photosensitive material is exposed by light modulated by a spatial optical modulation device, which is capable of securing high light utility efficiency and extinction ratio. In an image exposing apparatus including a spatial optical modulation device 50, such as a DMD having multitudes of reflective pixel sections disposed two-dimensionally, each for modulating light irradiated thereon; a light source 66 for irradiating light B on the spatial optical modulation device 50; and an imaging optical system 51 for focusing an image represented by the light B transmitted via the spatial optical modulation device 50 on a photosensitive material 150, each of the pixel sections (e.g., micromirrors of DMD) is shaped like a concave or convex mirror that converges the light B used for image exposure.
