DEVELOPING BRUSH AND DEVELOPING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a developing brush or a developing apparatus which promotes movement of a developing solution in the brush to render the concentration of the ambient resin component nearer to a uniform state for reducing development irregularity and which scrapes off an unhardened part of a photosensitive resin plate. SOLUTION: The developing brush aims to scrape off an unhardened part of a photosensitive resin plate and has a brush groove 3. The brush groove 3 functions as a passage for a developing solution having high concentration of the resin component or a developing solution having low concentration of the resin component (or containing no resin component) to prevent the developing solution from remaining in the developing brush submerged in the developing solution. Thereby, the concentration of the resin component in the brush is made uniform and irregular development of the photosensitive resin plate is decreased. COPYRIGHT: (C)2005,JPO&NCIPI
