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 7):
The lens unit according to  claim 6 , further comprising a light blocking member that includes a plurality of openings each having an opening radius RA and is disposed between the first lens array and the second lens array, wherein\n the plurality of openings of the light blocking member face the plurality of first lenses and the plurality of second lenses, the first lens array and the second lens array are formed of material that allows light to pass through, and the first lens array and the second lens array satisfies\n 0.45\u00d7\u0394 FB\u2264\u0394F\u2264 1.79\u00d7\u0394 FB,  \n where \u0394F represents each of a first difference between the first paraxial focal length and the first contour focal length and a second difference between the second paraxial focal length and the second contour focal length, \u0394FB is determined by \u0394 \ue89e \ue89e FB = n \ue89e \ue89e FE - n 2 \ue89e FE 2 - ( K - 1 ) 2 \ue89e RA 2 K , n represents a refractive index of the first lens array and the second lens array, FE represents each of the first contour focal length and the second contour focal length, PI represents a distance from each of principal planes of the second lenses to the image formation surface, FA represents each of the first paraxial focal length and the second paraxial focal length, and K represents a ratio PI/FA.
