PROBLEM TO BE SOLVED: To provide a developing method for reducing a further load on the purification apparatus of the company by treating wastewater overflowing developing section and rinsing section of an automatic developing device to make the quality of the wastewater tolerable enough to discharge the wastewater to a river. SOLUTION: (1) The developing method includes the process wherein a planographic printing plate having a silicone layer is developed in the automatic developing device having a pretreatment section, developing section, posttreatment section, and rinsing section, and also wherein the wastewater from the developing section and rinsing section undergoes an adsorbing treatment in an activated carbon treatment tank containing only activated carbon. (2) The developing method of (1) further includes the process wherein the wastewater which has undergone the adsorbing treatment in the activated carbon treatment tank is charged again to the developing section and rinsing section of the automatic developing device. (3) The developing method of (1) or (2) further includes the process wherein the wastewater from the developing section and rinsing section is delivered to the activated carbon treatment tank only when the wastewater stored beforehand in a wastewater storing tank reaches a specified volume.
