(C) Problem to be Solved by the Invention In general, the spacer of the photoreceptor coating device as described above is manufactured by cutting an aluminum alloy.
Aluminum alloy spacers have low surface hardness, so
During the above-mentioned cleaning, there was a drawback that the baskets and spacers collided with each other, resulting in scratches on the surface of the spacers. A spacer with a scratched surface may cause foreign matter to enter the photosensitive liquid during coating operation or may damage the ring-shaped blade. Scratches from the ring-shaped blade can cause damage to the outside of the cylindrical substrate to which the coating is applied.Therefore, an object of the present invention is to provide a photoconductor coating device equipped with a spacer that will not be damaged by cleaning or the like.

While the outer peripheral surface of the cylindrical base of the photoreceptor is brought into sliding contact, the upper and lower sides of the cylindrical base are held by spacers, and the photosensitive liquid stored in the coating liquid container is passed through in the axial direction, thereby forming the cylindrical base. In the photoreceptor coating device for applying the photoreceptor to the photoreceptor, the spacer is subjected to hard alumite treatment.
