PROBLEM TO BE SOLVED: To provide a coating film forming apparatus highly accurately holding an endless belt-like coating object used for a ring coating method without using a complicated structure, in a complete round state and keeping a gap to a coating nozzle tip uniform in the circumferential direction, thereby forming a stable coating film. SOLUTION: This coating film forming apparatus forming a coating film on the surface of the coating object 1 is provided with the endless belt-like coating object 1; a circular column-like member 2 inserted into the coating object; a liquid feeding means 6 to make a liquid to flow between the outer face of the circular column-like member 2 and the inner face of the coating object 1; a ring-like paint feeding nozzle 8 relatively moving along the axis of the circular column-like member 2 in relation to the coating object 1; an outer diameter measuring means 13 measuring the outer diameter of the coating object 1; and a pressure control means 7 controlling the supply pressure of fluid such that the outer diameter of the coating object 1 become fixed, according to the measuring result of the outer diameter measuring means 13.
