PURPOSE:To easily execute the maintenance check of each tank, and to carry exactly a photosensitive material by providing a positioning member engaged to an outside unit and an inside unit, respectively, so that it can be drawn out. CONSTITUTION:Developing tanks 41, 42, a bleaching fixing tank 43 and stabilizing tanks 44, 45 consist of outside tank units 410-450, and inside tank units 411-451, respectively, and the whole constitutes a developing treatment part. Each inside and outside tank can be attached and detached freely and at the time of inserting the inside tanks 411, 421 into the outside tanks 410, 420, both shaft ends r4e, r7e are fitted to bearing parts 410E, 410F, and the respective upper end parts of the outside tank and the inner tank are coupled by a hole and a pin, by which positioning is executed. Other inside and outside tanks are also attached and detached in the same way. Accordingly, each outside and inside tank can be attached and detached freely even against a liquid tank 401, the maintenance check is executed easily, the inside and outside tanks are positioned exactly to each other, and a photosensitive material is led exactly to each roller R of the outside tank and each roller (r) of the inside, therefore, no carrying failure occurs.
