摘要:
A line head, includes: a plurality of light emitting elements that are grouped into light emitting element groups, and an array that includes a plurality of imaging optical systems provided with respect to each light emitting element group which focus light beams emitted from the light emitting element groups toward a latent image-forming surface being conveyed in a second direction normal to or substantially normal to a first direction, wherein the plurality of imaging optical systems face positions on the latent image-forming surface mutually different in the second direction, and the respective imaging optical systems are constructed in accordance with differences in facing positions on the latent image-forming surface in the second direction.
