Abstract: Provided is a photographic processing device comprising at least one pair of a tray section and an upper section, which are each made by integral molding, arranged so as to form a space. A photosensitive material is passed through the space with its emulsion side turned to the upper plane of the tray section. The upper plane of the tray section and the lower plane of the upper section are equipped with free-rotation rollers for supporting the conveyance of a photographic material. For the adaptation to the width of a photosensitive material to be passed therethrough, two or more of the pairs of the sections are joined together in the width direction with packing.
