Abstract

PURPOSE:To eliminate unevenness in feeding a developing solution to improve development, by forming a feed nozzle into a pipe shape of necessary thickness by heat pressing spherical small particles to bond with one another, connecting this nozzle with a developer feed pump, and feeding it without liquid pressure. CONSTITUTION:Spherical small particles 1 smaller than millet grains are filled between an inside cylinder of necessary diameter and an outside cylinder for forming pipe thickness, heat pressed to fuse the contact points of the particles, and thus pipe-shaped feed nozzle (A) of desired thickness is obtained. This nozzle (A) has innumerable curved labyrinth through holes connected from the inside periphery to the outside one through the gaps among the particles, and this nozzle (A) is arranged in the central important position among the group of rollers 6 for moving photographic film 5 in a developing tank, and connected with developer feed pump 7 to feed the developer without liquid pressure toward film 5 passing through the developer and agitates it like a fountain.
