Abstract:
A developer efficiently removes photosensitive resin components dispersing in a developing solution. The developer includes a feeder that feeds a developing solution to a printing raw plate, a dispersed-material filter, wherein the developing solution in which a photosensitive resin composition separated from a photosensitive resin composition layer of the printing raw plate is dispersed, is passed through the dispersed-material filter to flocculate the photosensitive resin composition dispersing in the developing solution and a flocculated-material-filter removes the flocculated photosensitive resin composition from the developing solution passed through the dispersed-material filter.
