ABSTRACT:
A position setting apparatus for positioning a drum so that it may be uniformly coated with a photosensitive coating liquid to produce a photoreceptor, wherein the position of the drum is set by centripetally blowing a pressurized fluid from a fluid outlet means directly against the drum. The drum is positioned by the balance of the pressure of the blown fluid, and the surface of the drum is thereby protected from scratching as no mechanical device is required to touch the drum during positioning.
