Method of developing photosensitive planographic printing plate

摘要

A method of developing a photosensitive planographic printing plate which includes a support and a recording layer and which has been exposed to a light beam with a developer, wherein the photosensitive planographic printing plate is immersed in the developer while being conveyed, and development is accelerated by brushing the immersed photosensitive planographic printing plate with a brush member produced by winding, around a peripheral surface of an axially rotating roller, a brushing band composed of a sheet-like substrate containing a hairy material woven therein.
