PROBLEM TO BE SOLVED: To provide a coating film forming method which can more efficiently suppress generation of thickness unevenness of a coating film in forming the coating film on a peripheral surface of a base body.SOLUTION: A coating film forming method includes: a coating film forming process of a first liquid in which a nozzle and a base body are relatively moved in an axial direction of the base body with respect to the cylindrical or columnar base body which relatively rotates with respect to the nozzle, and also the first liquid is supplied from the nozzle to form a coating film of the first liquid; and a liquid film forming process of a second liquid in which a member including the second liquid and the base body are relatively rotated and the member and the base body are relatively moved in the axial direction of the base body prior to supply of the first liquid from the nozzle to a peripheral surface of the base body, and also the member is pressed to the peripheral surface of the base body to form a liquid film of the second liquid on the peripheral surface of the base body. The coating film forming process of the first liquid includes a process of supplying the first liquid from the nozzle onto the second liquid film, forming beads of the first liquid between the nozzle and the second liquid film, and spreading the beads in a circumferential direction of the base body. 【課題】本発明は、基体の周面への塗膜の形成にあたって、該塗膜への厚みムラの発生をより良く抑制することのできる塗膜形成方法を提供する。【解決手段】本発明の塗膜形成方法は、ノズルに対して相対的に回転している円筒状または円柱状の基体に対して、ノズルと基体とを基体の軸方向に相対的に移動させつつ、ノズルから第一液体を供給し、第一液体の塗膜を形成する第一液体の塗膜形成工程を有し、ノズルからの第一液体の基体の周面への供給に先立って、第二液体を含む部材と基体を相対的に回転させ、かつ該部材と基体とを基体の軸方向に相対的に移動させつつ、該部材を基体の周面に押し付けて、第二液体の液膜を基体の周面に形成する第二液体の液膜形成工程を有し、第一液体の塗膜形成工程は、該ノズルからの第一の液体を、第二液膜上に供給し、ノズルと第二液膜との間に第一液体のビードを形成し、該ビードを基体の周方向に塗り広げる工程を有する。【選択図】図１
