ABSTRACT:
A sheet-shaped photoconductor composed of a plurality of optical fibers is prepared by melt-spinning a spinning dope into optical fibers and, before the as-spun fibers are completely solidified, bonding the fibers to one another along the entire length thereof. The melt-spinning is carried out using a nozzle having a plurality of annularly arranged orifices. The as-spun fibers are arranged linearly in parallel to but not in contact with one another by using a grooved guide, and then the optical fibers are brought into contact with and fusion-bonded to one another by using a fusion bonding guide having a concave curved face in the central portion thereof, and the thus-formed sheet-shaped photoconductor is taken up.
