Abstract

The present invention provides an apparatus for producing an electrophotographic photosensitive member that has a coating machine for dipping plural members to be coated in a coating liquid in a coating bath and then lifting up the coated members to form a coating film on the surface of each of the plural members to be coated and a transport holding member for holding and transporting the members to be coated, and has plural stretching hoods which can individually cover each side of the plural members to be coated and can extend in association with the movement of the plural members to be coated to individually cover each side of the plural members to be coated when the coating machine is lifting up the plural members to be coated, wherein the plural stretching hoods are linked with each other at the lower parts of the hoods.

Claims

1. An apparatus for producing an electrophotographic photosensitive member, comprising:

a coating machine for dipping plural members to be coated in a coating liquid in a coating bath and then lifting up the coated members to form a coating film on the surface of each of the plural members to be coated; and

a transport holding member for holding and transporting the members to be coated,

and comprising plural stretching hoods which can individually cover each side of the plural members to be coated and can extend in association with the movement of the plural members to be coated to individually cover each side of the plural members to be coated when the coating machine is lifting up the plural members to be coated,

wherein the plural stretching hoods are linked with each other at the lower parts of the hoods.

2. The apparatus for producing an electrophotographic photosensitive member according to claim 1 wherein the production apparatus comprises the plural stretching hoods in a state where the plural stretching hoods are hanged from the coating machine or the transport holding member;

and the plural stretching hoods are linked with each other at the upper parts and at the lower parts of the hoods.

3. The apparatus for producing an electrophotographic photosensitive member according to claim 2 wherein the production apparatus comprises the plural stretching hoods in a state where the plural stretching hoods are hanged from the coating machine.

4. The apparatus for producing an electrophotographic photosensitive member according to claim 1 wherein each of the plural stretching hoods is a slide hood comprising plural cylinders.

5. The apparatus for producing an electrophotographic photosensitive member according to claim 1 wherein each of the plural stretching hoods is attached to the upper cover fixed on the coating bath at the lower parts of the hoods.

6. A process for producing an electrophotographic photosensitive member comprising forming a photosensitive layer on the surface of each of plural members to be coated by using a production apparatus according to claim 1.
