ABSTRACT:
The apparatus for coating a photosensitive material (M) with a processing liquid comprises an activator coating mechanism (43) for metering a constant amount of activator to apply the metered activator to the photosensitive surface of the photosensitive material fed by the pair of introduction rollers. The activator is supplied form a plurality of discharge holes (121) bored in a pipe (122) and is once received by a receiving portion (124). The activator is diffused horizontally and flows downwardly through a plurality of openings (123) bored at the bottom of the receiving portion onto a coating roller (125). The activator is diffused again at the contact between the coating roller and a diffusion film (126) and is coated to the photosensitive material by the coating roller.
