PURPOSE:To miniaturize a developing device, to reduce a cost, and also, to execute the development by uniform development density at high speed, and to prevent damage from being generated in developing paper and a photosensitive material by devising the shape of a stage and the position of a pass regulating means of the developing paper positioned before and after said stage. CONSTITUTION:A placing surface 8 on which the developing paper of a stage 7, etc., are placed is formed to a curved surface which has been displaced in the direction where both ends are separated from the developing paper, etc., in case of looking at from the direction intersecting orthgonally with the feeding direction of the developing paper, etc., and with regard to the feeding direction of the developing paper, etc., pass regulating means 9, 10 of the developing paper, etc., positioned immediately before and immediately after the stage 7 are arranged at a position corresponding to the anti-developing paper side from the nearest part 8a to the developing paper, etc., of the placing surface 8 of the stage 7. In such a way, the shape and the pressing force of rolls 55, 55' for bringing a photosensitive material 62 and developing paper 64 to press-contact with each other can be made considerably small, the developing device can be constituted so that it is miniaturized, light in weight and low in cost, and also, a beautiful development whose development density is uniform can be executed. Also, it is prevented that the developing paper and the photosensitive material are damaged by the stage and the edge of the roll.
