ABSTRACT:
A line head, includes: a lens array that includes a first lens, a second lens and a light transmissive substrate on which the first lens and the second lens are arranged in a first direction; and a light emitting element substrate on which light emitting elements are arranged in the first direction, wherein the first lens is formed such that, in a cross section in the first direction including an optical axis of an imaging optical system comprised of the first lens, a curvature of the first lens at an outer peripheral portion has a sign opposite to that of a curvature of the first lens on the optical axis or has a smaller absolute value than the curvature of the first lens on the optical axis.
