Here, the developing device 30B includes a developing unit 1, which is a place where development is performed, and a washing and rubber applying unit 8 for washing and applying rubber, and in this developing unit 1, a plate feeding table 14 A feeding roller 3 which pulls the plate fed from the platen into the developing unit 1, and a developing tank 2 for immersing and developing the plate fed by the feeding roller 3 in a developing solution; An intermediate feed roller 4 for continuously moving the plate in the tank 2 to the next step, a rotating brush 7 for maintaining the development uniformly when developing the PS plate while being rotated, and in the developing tank 2 A squeeze roller 6 for preventing the developer from leaking to the next unit, a rinse solution applying roller 9 for applying the rinse solution to the plate conveyed through the developing tank 2, and a rinse solution to prevent leakage The squeeze roller 10 and the plate which the image development completed are discharged to It consists of an ice board 15.

The developing unit 1 is provided with a discharge valve 11 through which waste developing solution is discharged, and a rinse liquid tank 12 is provided at the lower end between the squeeze rollers 6 and 10. The bellows pump 13 which pumps and circulates toward the rinse liquid application roller 9 is attached.

In addition, the developing tank 2 was formed in a curved surface to increase the development time while minimizing the length of the developing unit 1.

The developing process in the developing apparatus 30B thus constructed is shown in FIG. 1C. In this case, when the PS plate is introduced into the developing unit 1 inside the developing apparatus through the plate feeding table 14, the feed roller 3 pulls the plate and guides the developing plate 2 into the developing tank 2. In this way, the plate introduced into the developing tank 2 is developed in the developing tank 2 containing the developer, and then drawn and moved by an intermediate feed roller 4 provided in the developing tank to maintain the developing state uniformly.
