Coating device, coating method, and method for manufacturing photoconductor

A coating device comprising:

• a coating liquid holding part, comprising a case, provided with an upper opening and a lower opening and holding a coating liquid that is supplied from a coating liquid supply part comprising a pipe;
• and
• an annular body that is disposed inside the coating liquid holding part,
• wherein the coating device is configured such that a cylindrical body is adapted to penetrate the upper opening and the lower opening of the coating liquid holding part and the cylindrical body is adapted to penetrate the annular body,
• wherein the coating liquid held by the coating liquid holding part is adapted to flow in from an upper side of the annular body and flow out from a lower side of the annular body based on a relative movement between the annular body and the cylindrical body,
• wherein the annular body being installed on an installation surface that intersects a direction of the relative movement, the annular body being relatively displaceable along the installation surface that intersects the direction of the relative movement,
• wherein the annular body is configured to be relatively displaceable with respect to the upper opening and the lower opening of the coating liquid holding part.
