Abstract
An automatic developing apparatus for developing a photosensitive material includes a processing section, a throughput detector, a processing agent supplier, a water supplier, a calculator, a timer and a controller. The processing section accommodates a processing solution for processing the photosensitive material. The processing solution comprises a solid processing agent dissolved in water. The throughput detector detects a throughput of the photosensitive material through the processing section, and generates detection signals when the throughput becomes a predetermined value. The processing agent supplier supplies the solid processing agent to the processing section, and the water supplier supplies water to the processing section. The calculator calculates an amount of evaporation water evaporated from the processing solution, and the timer generates timer signals when a predetermined time period elapses. The controller controls the processing agent supplier and the water supplier to respectively supply to the processing section the solid processing agent and an amount of water not greater than a first predetermined supply amount responsive to the detection signals. The first …
