Abstract

A photographic light-sensitive material processing method in which not only a low-replenishment process, a speedy process and a compensation process in addition to a standard process can be carried out, but replenishment can be performed appropriately for various types of film or the like. A plurality of color developers are accommodated in respective developing tanks. A controller sets conveyance paths to selectively convey light-sensitive materials to any one of the development tanks. Further, the controller controls the operations of replenishment pumps by calculating the appropriate replenishment rate in accordance with the quantity of processing of film through a conveyance quantity detection sensor, a density detection sensor, a memory and an arithmetic operation unit.
