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.

An apparatus for positioning and uniformly coating a drum to produce a photoreceptor drum, comprising: means for holding and for sliding the drum vertically in an upwardly axial direction of the drum; positioning means for positioning the drum at a desired position for uniform coating thereof, said positioning means comprising fluid outlet means circumferentially positioned around the drum for jetting pressurized fluid directly onto only uncoated portions of the drum so as to maintain the drum at said desired position thereof; and coating means for uniformly coating a coating solution on an external surface of the positioned drum; wherein said fluid outlet means of said positioning means are arranged to jet said pressurized fluid in a direction so that said pressurized fluid flows downward after contacting the uncoated portions of the drum, thereby preventing damage to coated portions of the drum.
