形成される。Into this coating liquid tank 2, a cylindrical aluminum support 4 whose opening at one or both ends is closed with a seal plug 3, such as a rubber stopper, is lowered from one side perpendicularly to the liquid level 1Δ. and immerse it in coating liquid 1. The immersed support 4 is prevented from entering the coating liquid 1 by the atmospheric pressure or the sealing plug 3, and is applied only to the outer peripheral surface, and after being pulled out from the coating liquid tank, a predetermined film is formed on the outer peripheral surface of the support. A thick organic photoconductor film is formed.

In particular, after the support 4 is immersed in the coating liquid 1, in the process of pulling it up, the liquid level, that is, the height from the bottom of the coating liquid tank 2 to the surface of the coating liquid 1, decreases significantly.
The volume above the liquid level in the coating liquid 1 increases, and this part is filled with the vapor of the easily evaporable solvent constituting the coating liquid 1, and the organic photosensitive material coated and formed on the outer circumferential surface of the support 4 by the vapor of the solvent. The conductive film melts and flows out, resulting in uneven film thickness and rough film surfaces.
