A coating apparatus comprises a coating vessel holding a coating liquid with a liquid leakage preventing member having an opening. A cylindrical member such as a cylindrical support for supporting a photosensitive member is inserted into the opening and the cylindrical member is moved relative to the coating liquid vessel in the vertical direction. A scraping member for scraping the coating liquid is at least partially immersed in the coating liquid, or is positioned above the surface of the coating liquid in the coating liquid vessel, the scraping member being almost concentric to the cylindrical member and movable in the radial direction of the cylindrical member. The cylindrical member is axially aligned with the scraping member using coating liquid pressure applied to the scraping member to coincide the center of the scraping member with the center of the cylindrical member. This invention provides an apparatus and method for forming a coated layer having a uniform layer thickness free of unevenness on the outer periphery of a cylindrical member such as an electrophotographic photosensitive support at a high production rate inexpensively.
A coating apparatus having a coating liquid vessel for holding a coating liquid with a liquid leakage preventing member having an opening, wherein a cylindrical member to be coated is inserted into the opening, and the cylindrical member is moved in a vertical direction relative to the coating liquid vessel to coat the outer periphery of the cylindrical member with the coating liquid, and a scraping member movable in a radial direction relative to said coating liquid vessel, said scraping member for scraping the coating liquid, said scraping member is concentric to the cylindrical member and is at least partially immersed in the coating liquid, or is positioned above the surface of the coating liquid in the coating liquid vessel, and said scraping member movable in the radial direction of the cylindrical member provided in the coating apparatus.
A method for coating a coating liquid on an outer peripheral surface of a cylindrical member in a coating liquid vessel for holding the coating liquid therein, equipped with a liquid leakage preventing member having an opening, comprising the steps of:
A coating apparatus for coating an electrophotographic photoreceptor comprising a coating liquid vessel with a liquid leakage preventing member having an opening, for holding a coating liquid for forming the photoreceptor, wherein a cylindrical support for the photoreceptor is inserted into the opening, and the cylindrical support is moved in a vertical direction, relative to the coating liquid vessel to coat the outer periphery of the cylindrical support with the coating liquid, and a scraping member movable in a radial direction relative to said coating liquid vessel for scraping the coating liquid for forming the photoreceptor, said scraping member is concentric to the cylindrical support and is at least partially immersed in the coating liquid, or is positioned above the surface of the coating liquid in the coating liquid vessel, and said scraping member movable in the radial direction of the cylindrical support provided in the coating apparatus.
