ABSTRACT:
An optical waveguide array includes a two-dimensionally refractive index profile lens for focusing light beams in a scanning direction. The two-dimensionally refractive index profile lens is bonded to or integrally formed with the optical waveguide array. The refractive index is distributed in the two-dimensionally refractive index profile lens by changing the irradiation energy of ultraviolet ray during the manufacture. As a member for focusing the light beams in the irradiation direction which is perpendicular to the scanning direction, another two-dimensionally refractive index profile lens or a cylindrical lens is used. The optical waveguide array with such an inexpensive structure can focus the light beams both in the scanning direction and the irradiation direction. The resolution of the latent image formed on a photosensitive member can thus be improved.
