The invention discloses an imaging department film developing device. The imaging department film developing device structurally comprises a supporting frame, a developing liquid storage barrel, a fixing bath storage barrel, a flushing barrel, an automatic film conveying device, a control panel, a film developing machine body, a maintenance cover, a developing chamber, a developing mechanism, a fixation chamber, a fixation mechanism, a flushing chamber, a flushing mechanism, a drying chamber, a drying device and a film outlet, wherein the developing liquid storage barrel, the fixing bath storage barrel and the flushing barrel are sequentially arrayed in a row from right to left and arranged in the lower portion of the supporting frame. The imaging department film developing device has the advantages that the automatic film conveying device is arranged and is capable of automatically and sequentially conveying blank films into the film developing machine body, elasticity of a keen spring is used for controlling the height of a lifting movable plate, and the film can be smoothly conveyed even if only one film is left over, the films are sequentially conveyed one by one by means of the distance between two film inlet rollers, it is prevented that the films are wasted as the films get stuck, the automation degree of the imaging department film developing device is effectively improved, the possibility that the films get stuck is reduced, the waste rate of the blank films is reduced, and high efficiency and quality of film developing are ensured.
