PURPOSE:To prevent defect in plate making by a dip developing method, to enable quick processing, to always supply a new processing solution efficiently, and to enable processing with a small quantity of waste processing solution so as to eliminate complicatedness in maintenance by supplying a developing solution to a developing solution applying part corresponding to the width of a plate so as to develop a photosensitive material. CONSTITUTION:A photosensitive material P is inserted from an inlet guide 7, and the cross- direction positional information is obtained from the material by a width detecting sensor 8 to control a driving motor 9. A processing liquid drop nozzle 4 is repeatedly moved between both ends in the cross direction of the photosensitive material P to supply the processing liquid, and the liquid is applied to the material by bar-like members 1. Though the nozzle is repeatedly moved between both ends in the cross direction of the photosensitive material P, the liquid staying in a gap between a pair of bar-like members 1 is about to spread regardless of any influence on the surface tension of the processing liquid, so that it is indifferent to shifting a little inside from the both end positions in the cross direction. Thus, the consumption amount can be reduced by applying the quantity of a processing liquid according to the plate size and always supplying a new processing liquid to the plate to prevent deterioration, so that the processing liquid is prevented from being spread to the unnecessary back of the plate. |
