Abstract:
A developing processing apparatus equipped with a blowoff chamber having jetting holes from which a processing solution is jetted toward an emulsion surface of a photosensitive material, wherein the jetting; holes are formed in such a manner that a hole diameter thereof is in a range of 0.5 mm to 0.9 mm and intervals thereof in a transverse direction of the photosensitive material are each in a range of 3.0 mm to 4.5 mm, and the jetting holes are arranged in a staggered manner in a direction in which the photosensitive material is conveyed; and a number of the jetting holes is set in accordance with capacity of a pump for sending the processing solution to the blowoff chamber so that flow velocity of the processing solution jetted from the jetting holes becomes a value in a ran e of 680 to 1,200 mm/sec.
