PROBLEM TO BE SOLVED: To improve processing performance of a processing liquid and to improve an agitation property when immersing a photosensitive material in the processing liquid stored in a processing tank and processing it. SOLUTION: In a development tank 24 formed in the processing tank 22, a developer is circulated and agitated by the developer jetted from spray pipes 54 and 56. Then, since the spray pipe 54 provided on an upstream part in a PS plate carrying direction jets a large amount of the developer toward a carrying width direction, the developer flows on a surface of a PS plate along a width direction, a development processing to the PS plate is accelerated and a temperature change of the developer due to the temperature of the PS plate is prevented. Also, since the spray pipe 56 provided on a downstream part of the development tank jets the developer from a jetting hole 204 to a downstream side of the carrying direction, the developer of an almost uniform processing performance is supplied along the width direction of the PS plate and irregularities of finishing are prevented. |
