Abstract:
Provided are a lens array, a lens unit, an exposure device, an LED head, and an image forming apparatus. The lens array includes a plurality of lenses arranged so as to form an array. Each of the plurality of lenses is configured so that a contour focal length which is a focal length of a ray incident on a first position separate from an optical axis is longer than a paraxial focal length which is a focal length of a ray incident on a second position in the vicinity of the optical axis.

Claim (Index 4):
A lens unit comprising:\n a first lens array including a plurality of first lenses arranged so as to form an array; and a second lens array including a plurality of second lenses arranged so as to form an array, wherein optical axes of the plurality of second lenses respectively coincide with optical axes of the plurality of first lenses, each of the plurality of first lenses is configured so that a first contour focal length which is a focal length of a ray incident on a first position separate from the optical axis is longer than a first paraxial focal length which is a focal length of a ray incident on a second position in the vicinity of the optical axis, and each of the plurality of second lenses is configured so that a second contour focal length which is a focal length of a ray incident on a third position separate from the optical axis is longer than a second paraxial focal length which is a focal length of a ray incident on a fourth position in the vicinity of the optical axis.
