Abstract:
A line head includes multiple light emitting element groups each including multiple light emitting elements. In each light emitting element group, the multiple light emitting elements are disposed in a two-dimensional arrangement so that a distance Gx is greater than a distance Gy. The light emitting element groups are arranged so that pitches Px are greater than pitches Py.
