PURPOSE:To stably develop the printing plate which has photosensitive layers on both surfaces of a base without any problem resulting from a development supplementation system and to reduce the consumption of a liquid developer by performing the development by holding the liquid developer by passing it between an upper guide plate and a lower guide plate which are arranged vertically at a fine distance nearby a conveyance path. CONSTITUTION:The liquid developer which is supplied is held on the plate surface of the photosensitive planographic printing plate by the upper guide plate 10 and lower guide plate 11, guided, and conveyed. The interval between a conveyor roller 5 and a squeeze roller 8 is set smaller than the minimum fixed form size of the photosensitive planographic printing plate, so the photosensitive planographic printing plate is pinched by either one and passes through the gap part 12. The photosensitive planographic printing plate exiting from the gap part 12 have the plate surface rubbed against brush rollers 7a and 7b and then squeezed to complete the development, and the plate is conveyed to a washing part 2 and then a rising gum part 3, so that respective processes are performed. |
