PURPOSE: To obtain an automated processor which eliminates the need for feed piping by providing each processing tank for a photosensitive material with a means which injects processing solution or washing water detachably.

CONSTITUTION: A feed water pump 41 and a cap 31C are lifted to set a cartridge 31 filled with the developing solution and returned to their original positions, and then the liquid feed pump 41 is put in operation. The developing solution in the inner bag 31B in the cartridge 31 is sent to a processing tank 11 through a hose connected to an U-type tube 11C. An overflowing solution is recovered in the space outside of the inner bag 31B in the cartridge 31F from a liquid receiving pipe 31F through a hose connected to an overflow pipe 11E. The washing processing system circulates the washing water by liquid feed pumps 44 and 45 in the order of the cartridge 34, the pump 44, a washing processing part 14, and the cartridge 34 and then circulates it in the cartridge 35 similarly. Thus, the processor which eliminates the need for feed piping is obtained.
