The invention discloses a developing machine for an imaging department. The developing machine for the imaging department structurally comprises a film outlet, a stage, a film inlet, a transmission drying mechanism, a bench, support feet and a housing. The support feet are welded to four corners of the bottom end of the bench, the housing is arranged on the bench, the stage is arranged on the housing, the top of the stage is provided with the film outlet, the bottom of the stage is provided with the film inlet, the transmission drying mechanism and a motor are arranged inside the housing, andthe transmission drying mechanism is mechanically connected with the motor. By providing the structures such as a sponge clamp, a first vacuum tube, a second vacuum tube and a reflow tube, the problemof friction between a transmission roller and the film during drying is solved; the sponge clamp can absorb liquid drops on the film and may also reduce friction; by using the vacuum suction principle herein, the wetting problem of the sponge clamp is solved, and the liquid drops can be recycled.
