ABSTRACT:
A film forming apparatus to form a coating film by applying a coating material to an outer circumferential surface of a cylindrical object to be coated, includes a material applying device having a nozzle unit to apply the coating material to the outer circumferential surface of the object and a material supplying unit to supply the coating material to the nozzle unit and a moving device configured to move the nozzle unit relatively to the object such that the coating material is applied uniformly to the outer circumferential surface of the object. The moving device includes an object holding unit configured to hold the object, a nozzle moving unit configured to move relatively the nozzle unit with respect to the object holding unit along a longitudinal axis of the object holding unit, and a guide unit configured to guide the nozzle unit along the object holding unit as the nozzle unit moves along the object holding unit such that an interval between the nozzle unit and the object is maintained constant.
