<p>The present invention provides an exposure apparatus which can improve quality of an image formed on a recording medium. The exposure apparatus comprises an array refracting element which divides a laser beam in a sub-scanning direction on a light path of the laser beam between an emission opening of the laser beam and a recording film, and in which a pair of refracting members are formed to be arranged in a line, and a focal distance f of a condenser lens, a wavelength lambda of the light beam, and a width d for the division direction of a divided region of the laser beam in the refracting member are determined so that a value (fx lambda )/d obtained by dividing a product value of the focal distance f and the wavelength lambda by the width d is not more than a predetermined value. <IMAGE></p> |
