ABSTRACT:
A silver halide photosensitive material after exposure can be efficiently processed in a multi-compartment apparatus comprising a series of processing compartments interconnected through narrow channels to define a continuous processing path, by passing the photosensitive material through the series of compartments along the path. Two or more processing solutions of different compositions are supplied to the path at different positions to fill the compartment with the solutions, while the solution is discharged from the path through an outlet port at an intermediate position. During a quiescent period, the solution is discharged such that the compartment which the photosensitive material first enters and the compartment from which the photosensitive material exits become empty. Operation is restarted by refilling the entrance and exit compartments with fresh solutions.
