<P>PROBLEM TO BE SOLVED: To provide a liquid film thickness measuring apparatus capable of easily and accurately measuring whether the thickness of a liquid film formed on the surface of a roller is uniform in the width direction of the roller or not. <P>SOLUTION: While a blade 24 is pressed to the surface of the roller such as a transfer roller 11, the roller is rotated for a specific time. The water film formed on the surface of the roller is thereby scraped off by the blade 24. On the basis of the volume of the scraped off water, whether the thickness of the water film formed on the surface of the roller is uniform in the width direction of the roller or not is measured. The liquid scraped off from the surface of the roller such as the transfer roller 11, and stored in a storage section 21a is once caused to flow into a measuring section 27 and an operator measures the volume of the liquid in the measuring section 27. <P>COPYRIGHT: (C)2009,JPO&INPIT |
