PURPOSE:To replenish always a replenishing liquid properly, by comparing transmitted light quantity data for passage of photosensitive materials with that for non-passage of them to measure a blackening area of photosensitive materials and replenishing the quantity of the replenishing liquid proportional to the measured value. CONSTITUTION:The photoelectric output corresponding to the quantity of the transmitted light of photosensitive materials 20 is converted to a digital quantity in an AD converter 41 and is inputted to a microcomputer 40. Clock pulses from a pulse oscillator 42 are inputted to the microcomputer 40 and on the basis of the operation processing result of the microcomputer 40, a developer is supplied to a development processing tank 21 through a developer supply device 43, and a prescribed quantity of a fixer is supplied to a fixing processing tank 22 through a fixer replenishing device 44. |
