Summary:PROBLEM TO BE SOLVED: To reduce the carrying load and the load fluctuation of a carrying means and to reduce the fluctuation of the carrying speed when an instant film is ejected while being developed by supporting a developing means so that it can be moved forward and backward in the carrying direction of the instant film within a prescribed range and elastically holding it at the almost center of the prescribed range. SOLUTION: Guide parts 2a and 2b for movably supporting developing rollers 6a and 6b in the carrying direction of the instant film and in the reverse directions are formed at a left and a right frame bodies 2. A developing roller frame body 8 is respectively fitted to the guide parts 2a and 2b and the guide pins 8a and 8b thereof are respectively slidably engaged in the guide parts 2a and 2b of the frame body 2. A developing means elastic holding member 9 is fixed to the frame body 2 and a 1st pressing part 9a pressing the rollers 6a and 6b in the carrying direction of the instant film and a 2nd pressing part 9b pressing them in the reverse directions are formed at the frame body 2. Then, the rollers 6a and 6b are interposed at the center of the movable range by the 1st and the 2nd pressing parts 9a and 9b.
