    Abstract: The present invention provides an apparatus and a method for forming a uniform and smooth coating film on a surface of a cylindrical body, for example, for production of an electrophotographic photosensitive body. The apparatus of the present invention includes a float having a space portion formed in the inside thereof for floatation in the liquid surface of the paint. The float is specifically formed so that even in the case where the paint contains a solvent that gradually evaporates, no bubbles are generated from a lower portion of a hollow cylindrical body during the coating step, because the pressure rising inside the hollow cylindrical body is moderated by the space portion of the float.
