## 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

### Claim 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;
a transport holding member for holding and transporting the plural members to be coated; and
plural stretching hoods which individually cover each side of the plural members to be coated and 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 plural slide hoods comprising plural cylinders,
the plural slide hoods are in a state where the plural slide hoods are hanged from the coating machine or the transport holding member, and
the plural slide hoods are linked with each other at the uppermost cylinder of the plural cylinders of each slide hood and at the lowermost cylinder of the plural cylinders of each slide hood.

### Claim 2 (depends on 1)

The apparatus for producing an electrophotographic photosensitive member according to claim 1, wherein the apparatus comprises the plural slide hoods in a state where the plural slide hoods are hanged from the coating machine.

### Claim 3 (depends on 1)

The apparatus for producing an electrophotographic photosensitive member according to claim 1, wherein the lowermost cylinder of the plural cylinders of each slide hood is detached from an upper cover fixed on the coating bath.

### Claim 4

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;
a transport holding member for holding and transporting the members to be coated; and
plural stretching hoods which individually cover each side of the plural members to be coated and 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 plural accordion-like hoods,
the plural accordion-like hoods are in a state where the plural accordion-like hoods are hanged from the coating machine or the transport holding member, and
the plural accordion-like hoods are linked with each other at the upper part of each accordion-like hood and at the lower part of each accordion-like hood.

### Claim 5 (depends on 4)

The apparatus for producing an electrophotographic photosensitive member according to claim 4, wherein the lower part of each accordion-like hood is detached from an upper cover fixed on the coating bath.

### Claim 6 (depends on 4)

The apparatus for producing an electrophotographic photosensitive member according to claim 4, wherein the apparatus comprises the plural accordion-like hoods in a state where the plural accordion-like hoods are hanged from the coating machine.
