An exposing device according to an embodiment includes: a light emitter; a first light blocking member including first apertures; a first lens array including first lenses, wherein each of the first lenses converges the light passing through the corresponding first aperture; a second light blocking member including second apertures; and a second lens array including second lenses, wherein each of the second lenses converges the light passing through the corresponding second aperture. An optical axis of each of the first lenses and an optical axis of the corresponding one of the second lenses substantially coincide with each other. A first aperture center of each of the first apertures and a second aperture center of the corresponding second aperture are disposed at a predetermined distance from the optical axis of the corresponding first lens and the optical axis of the corresponding second lens in an array direction of the light emitter.
