An electrophotographic photosensitive member is manufactured by applying a photosensitive material to a peripheral surface of a drum-shaped photosensitive substrate. As a coating method, usually, a container (immersion coating tank) containing a coating solution of a photoconductor material and a photoconductor substrate are relatively moved so that the photoconductor substrate is immersed in the coating solution, and then pulled up. Then, a method is employed in which the pulled-up photosensitive substrate is allowed to stand still, air-dried (touch drying), and then completely dried in an oven or the like. In order to produce an electrophotographic photosensitive member having a uniform thickness of the photosensitive coating film in a short time, a quick-drying solvent is usually used as a solvent for the coating solution.

When a quick-drying solvent is used, the coating liquid can be solidified in a short period of time by increasing the drying speed of the coating solution. Even in the air flow, the turbulence of the solvent vapor generated thereby causes unevenness in the thickness of the formed photosensitive coating film. The use of such a photoreceptor causes problems such as image unevenness, whitening, and background contamination due to toner adhesion.

In many conventional dip coating apparatuses using a stretchable cover, when the sliding portion of the stretchable cover is made of resin, the outer wall of the cover is also made of resin. There is no structure whose outer wall is made of metal. When the sliding portion and the outer wall of the telescopic cover are both made of resin, there is a problem that static electricity is accumulated due to repeated expansion and contraction, which is extremely dangerous in the production of an electrophotographic photosensitive member using a solvent. If both the sliding portion and the outer wall of the cover are made of metal, metal dust is generated, and if this metal powder adheres to the photoreceptor, a leak failure occurs and the photoreceptor becomes defective, resulting in a low production yield. There was a problem of lowering.
