ABSTRACT:
A method of and an apparatus for developing with a developer a photosensitive lithographic plate on which images have been exposed while transporting the photosensitive lithographic plate with one surface thereof facing roughly downwards. In the method and the apparatus, while the photosensitive lithographic plate coated with the developer is being transported in a transport path which accommodates a portion of the developer and which is curved in a downward projecting manner, the photosensitive lithographic plate is dipped in the accommodated developer and, at the same time, the development of the layers of the photosensitive lithographic plate is accelerated by rubbing them. Moreover, the developer in the transport path is replenished with the developer which has been applied to the photosensitive lithographic plate. Accordingly, it is not necessary to provide a developer replenishing device in the transport path.
