Image forming apparatus

An image forming apparatus comprising:

• a plurality of optical fibers each having a first end and second end;
• a plurality of semiconductor laser modules each mounted on the first end of each of the optical fibers, the plurality of semiconductor laser modules for emitting a beam emitted from a semiconductor laser toward the second end of each of the optical fibers;
• an optical fiber arrangement portion for arranging therein the second ends of the optical fibers;
• and
• a scanning optical system for recording and forming an electrostatic latent image on a photosensitive member using a plurality of beams emitted from the optical fiber arrangement portion;
• wherein the optical fiber arrangement portion comprises a plurality of plate members disposed on the outer peripheral portion of the optical fibers, respectively, and the plurality of plate member is used when the optical fiber arrangement portion is assembled;
• and
• wherein the plate members are superposed one on another in parallel to each other to form an optical fiber array in the optical fiber arrangement portion.
