PROBLEM TO BE SOLVED: To continuously take up a thin film web intermittently fed out from an image forming apparatus without causing winding tightening and creases. SOLUTION: A thin film web take-up apparatus includes a take-up roller taking up the thin film web intermittently fed out from the image forming apparatus. The take-up roller is driven by a take-up motor. The take-up amount of the take-up roller is detected by a take-up sensor. The thin film web take-up apparatus has a dancer roller which is oscillatably supported between the image forming device and the take-up roller and is brought into contact with the thin film web to sag it while applying tension to the thin film web. Angles which are formed by the thin film web just before and after the thin film web comes into contact with the dancer roller, are detected by an angle detection section. The angles are adjusted by an angle adjustment mechanism. The thin film web take-up apparatus has a control section controlling the rotating speed of the take-up motor and the angle adjustment mechanism on the basis of detection results of the take-up sensor and detection results of the angle detection section.
