Patent ID: 8875654

Claim:
An apparatus for manufacturing a cylindrical member, the apparatus comprising: a cylindrical core body having a releasing layer coated over an entire outer peripheral surface of the core body; a film-forming device configured to form a resin film in a central region of the releasing layer, the central region being located at a central portion from both ends in the axial direction of the outer peripheral surface of the core body; a judging device configured to judge, based upon a number of times of manufacturing the cylindrical member, a releasing property of outer regions of the releasing layer, the outer regions being continuous from the central region where the resin film is to be formed to both ends in the axial direction of the outer peripheral surface of the core body, before the resin film is formed by the film-fanning device; and a control device that receives the results of the judgment by the judging device and is programmed to control the film-forming device so that the resin film is formed by exposing regions of the releasing layer on both ends in the axial direction of the outer peripheral surface of the core body, and is programmed to control a coating starting position and a coating ending position depending on the judgment results, wherein the releasing property is determined by comparing the number of times of manufacturing to a predetermined value; and if the releasing property is judged to be deteriorated, the coating starting and ending positions are shifted increasingly towards the central portion of the core body as the number of times of manufacture increases.
