Exposure apparatus

An exposure apparatus, comprising:

• i) a light source for producing a light beam,
• ii) a light modulating section, which is constituted of a plurality of arrayed light modulating units, each of the light modulating units comprising:
• a) multiple kinds of filtering devices, which perform filtering operations on the light beam having been radiated out from the light source such that the filtering devices transmit light components of the light beam having wavelengths falling within different wavelength ranges, and each of which radiates the corresponding transmitted light component into end of an optical fiber of an optical fiber group, and
• b) a plurality of light modulating devices, each of which modulates the light beam incident upon the corresponding one of the filtering devices,
• iii) an exposure head, which is located so as to stand facing a photosensitive surface of a photosensitive material capable of being conveyed, and to which the other end of each optical fiber of the optical fiber group is connected, and
• iv) a driving mechanism for moving the exposure head in a straight line along a direction, which is normal to the direction of conveyance of the photosensitive material.
