摘要： A devleoping device for photosensitive materials, particularly, for photosensitive materials used flat printing plates, in which the consumption rate of the developing solution is significantly reduced. The developing solution is applied to the exposed surface of the heated photosensitive material and excess portions thereof quickly removed before the temperature of the photosensitive material is significantly lowered or the temperature of the developing solution significantly raised. The excess portons of the developing solution are recycled.

摘要： A method for supplementing a replenisher for developer which comprises developing a large number of PS plates imagewise exposed to light with a developer composed of an aqueous solution containing electrolytes in an automatic developing machine, characterized by determining an AC impedance of the developer contained in the automatic developing machine, obtaining a correction impedance from the measured impedance value and rate of replacement and supplementing a desired amount of the replenisher to the developer when the correction impedance reaches a predetermined value. This method makes it possible to maintain a desired activity of the developer even when a large number of PS plates are processed and to relax the restriction on the incorporation of optional devices such as an autofeeder into the automatic developing machine.

摘要： A light sensitive material processing apparatus for applying a finisher onto obverse and reverse surfaces of an image-exposed sheet-like, light-sensitive material while the light-sensitive material is being conveyed with one surface of the light-sensitive material facing substantially upward after the light-sensitive material has been developed, during automatic conveyance of the light-sensitive material. The apparatus includes a first processing device for applying the finisher onto the one surface of the light-sensitive material and holding the finisher in a state in which the finisher is placed on the one surface for a predetermined time so as to effect processing of the one surface; and a second processing device for applying the finisher onto another surface of the light-sensitive material and for maintaining a state of contact between the finisher and the other surface for a time substantially equal to the predetermined time so as to effect processing of the other surface. Accordingly, surfaces both of the light-sensitive material are uniformly processed by the finisher.

摘要： A method of and an apparatus for developing with a developer a photosensitive lithographic plate on which images have been exposed while transporting the photosensitive lithographic plate with one surface thereof facing roughly downwards. In the method and the apparatus, while the photosensitive lithographic plate coated with the developer is being transported in a transport path which accommodates a portion of the developer and which is curved in a downward projecting manner, the photosensitive lithographic plate is dipped in the accommodated developer and, at the same time, the development of the layers of the photosensitive lithographic plate is accelerated by rubbing them. Moreover, the developer in the transport path is replenished with the developer which has been applied to the photosensitive lithographic plate. Accordingly, it is not necessary to provide a developer replenishing device in the transport path.
