PURPOSE:To reduce the size of the shape and pressing force of a pressure applying means and to reduce the size and weight of the developing device by moving a roller as a constituent element of the pressure applying means for pressing a photosensitive material and a developing material against each other so that the photosensitive material and developing material are scanned. CONSTITUTION:A stage roller 11 presses the photosensitive film 3 and developing paper 4 with a pressure roller and also cooperates with a paper pressure roller to feed the photosensitive film 3 and developing paper 4. When a conveyance belt 43 runs, a moving block 50 is moved right and left together with a carriage 51 and the pressure rolls 66 and 66' roll while pressed against the pressure receiving surface 12a of the stage roller 11. When a photosensor 44 detects the moving block 50 reaching one end or the other end of its movement range, a motor 37 is rotated forward and backward alternately and the moving block 50 moves between both ends of the movement range intermittently. |
