ABSTRACT:
A developing apparatus for effecting development by supplying a developing solution to a developing area of a light-sensitive material has a multiple-hole plate; a pressurizing chamber disposed on one side of the multiple-hole plate and adapted to pressurize the developing solution; and a vibrating device for pressurizing the developing solution by vibrating the multiple-hole plate so as to cause the developing solution to be jetted and supplied to the developing area in the form of droplets through the holes of the multiple-hole plate. Accordingly, the amount of the developing solution supplied wastefully is minimized.
