ABSTRACT:
An exposure device includes a first light source column, a second light source column, and a light converger. A distance along a first direction between the center of a first light source of the first light source column and the center of a second light source of the second light source column, which is located to a second direction relative to the first light source, is larger than a distance along the first direction between the center of a third light source of the first light source column, which is located farther from an optical axis of the light converger than the first light source and the center of a fourth light source of the second light source column, which is located to the second direction relative to the third light source.
