In recent years, the development of medical X-ray film is done by Automatic X-ray film processor which was exploited for fulfilling the need of rapidity, uniformity and etc.. As to rapidity, an appearance of Automatic X-ray film processor of 90 second type satisfied us. Control of treatment has been studied by many people. But the change of density image on film treated by Automatic X-ray film processor was not called in question. The disturbance in the directions on film density treated by Automatic X-ray film processor was studied in comparison of two density spread functions, i.e., parallel and right angles to the roller. In the result of expeariment, the density spread functions were different in parallel and in right angles to the roller. And it became clear that the density spread functions treated by Automatic X-ray film processor were thiner than the slit width.
