ABSTRACT:
An optical scanning device comprising a light source for emitting a light beam on the basis of the image information, an optical waveguide array including plural optical waveguides each comprising a core portion formed at the center portion thereof for guiding the light beam from the light source therealong and a cladding portion formed so as to surround the core portion and each having a light incident end for receiving the light beam from the light source and a light emitting end for emitting the light beam guided along the core portion, and a polygonal mirror for successively distributing the light beam having the image information to each of the light incident ends of the optical waveguides in a spot form. The optical waveguides are arranged in such a manner that an interval between centers of neighboring cores is smaller than a spot diameter of the light beam incident to the light incident end of each of the optical waveguides.
