METHOD FOR DEVELOPMENT PROCESSING OF NON-SILVER SALT PHOTOSENSITIVE MATERIAL WHICH IS IMPROVED IN UNIFORMITY OF DEVELOPMENT

PURPOSE:To uniformize the amt. of a developing soln. to be coated by ejecting the developing soln. from a slit formed of two sheets of plate materials and coating the soln. via a roller on a photosensitive material. CONSTITUTION:The exposed non-silver salt photosensitive material 1 is nipped by a coating roller pair 2 and is conveyed. The unused developing soln. in a tank 7 is then fed by a pump 8 to a nozzle pipe 5 and the developing soln. flowing down from the pipe 5 is dropped along the inside wall of the slit 4 so that the developing soln. is coated from the bottom thereof onto the material 1 via the roller 2. The material 1 is conveyed by an inclined roller 3 preferably at an upward angle toward the conveying direction and is fed into a washing tank 14. The slit 14 is designed to be adjustable in the gap thereof and at least one of two sheets of the plate materials constituting the slit 4 is formable of a flexible material.
