ABSTRACT:
A developing apparatus wherein a hollow drum-shaped conveyor has an internal partition with a set of tubular receptacles for exposed photosensitive material. The partition and one end wall of the conveyor define a chamber the lower portion of which contains a supply of liquid, and each receptacle has an open end in communication with the chamber. When the conveyor is set in rotary motion, the open ends of successive receptacles dip into the supply of liquid and scoop up some liquid which then flows out of the receptacles while they rise above and thereupon descend back toward the supply of liquid. Such liquid can be caused to indirectly exchange heat with water which is confined in a compartment at the other side of the partition and/or in a trough into which the lower portion of the rotating conveyor is immersed.
