PURPOSE:To execute a stable development, and also, to reduce the consumption of a developer by providing a heating means for heating a photosensitive material before supplying the developer, a weighing means for supplying the developer by a necessary quantity to the exposing surface of the photosensitive material, and a developing area for developing the photosensitive material by a weighed developer. CONSTITUTION:A photosensitive material 10 is heated by a heating means 11, and a developer 30 is supplied thereon by a spray 26, and removed by leaving only a prescribed quantity by a clearance formed between the outside periphery of a developer weighing means, namely, a wire 50, and a guide roller 24. As for the photosensitive material 10 which has passed through the weighing means, its development processing is executed in an area 16 by the developer 30 which has been left by a prescribed quantity. The developer 30 is heated by which the photosensitive material 10 has, therefore, its developing effect is high, and as for the developer 30 after the development, its development fatigue and the fatigue degree caused by a contact with air are high, therefore, said developer is non-returnable. In such a way, the developer 30 which is brought to circulating use generates no fatigue, and the developer 30 being free from fatigue is always supplied, therefore, a stable development is executed, and also, the consumption of the developer 30 is reduced. |
