COATING APPARATUS, COATING METHOD, AND METHOD OF MANUFACTURING PHOTORECEPTOR

Japanese Patent JP2023141320

A

To obtain a coating apparatus which suppresses the occurrence of foreign matter defects of a coating film on an outer peripheral surface of a cylindrical body and suppresses the occurrence of coating unevenness of the coating film on the outer peripheral surface of the cylindrical body.SOLUTION: A coating apparatus 10 includes: a coating liquid holding part 12 which is provided with an upper opening part 25 and a lower opening part 28, where a coating liquid L is held and an outer circumference 100A of a cylindrical body 100 is coated with a coating liquid L by relatively moving the cylindrical body 100 upward in a vertical direction; a circulation part 16 for supplying the coating liquid L to the coating liquid holding part 12; and a moving device 80 for relatively moving the cylindrical body 100 in the vertical direction with respect to the coating liquid holding part 16. In the circulation part 16 and the moving device 80, the supply amount and the moving speed are set such that relative speed V of the coating liquid L flowing down along the outer peripheral surface 100A of the cylindrical body 100 is 10 mm/s or more and 200 mm/s or less when the cylindrical body 100 is relatively moved upward in the vertical direction.SELECTED DRAWING: Figure 1
