PROBLEM TO BE SOLVED: To execute the developing processing of a printing plate used for an efficient printing under the condition that a developing processing device is miniaturized and simplified. SOLUTION: A developing processing device 26 is equipped with a developing part 371 having a developing roller 374 for applying a developing solution to a printing plate held on the outer peripheral part of a first plate cylinder 11 or a second plate cylinder 12 moved to an image recording position for developing processing, a fixing part 372 having a fixing roller 375 for applying a fixer to this printing plate for fixing processing and a squeezing part 373 having a squeezing roller 376 for removing the developing solution or the fixer from the printing plate and a brushing roller 377 for cleaning this squeezing roller 371. These developing part 371, the fixing part 372 and the squeezing part 313 are transferred between an developing processing position and a retreated position by means of an developing processing device transferring mechanism. |
