Abstract
An image forming elements array includes a plurality of image forming elements which are integrated with each other and are arranged to extend in an arrangement direction so as to generate an image having common magnification. When the distance along the optical axis from an object plane to the incident surface of the image forming element is represented by L and the distance along the optical axis from the incident surface to the emerging surface is represented by T, a condition 0.20≦T/L≦0.50 is satisfied.
