PROBLEM TO BE SOLVED: To provide a printing device by which the uniformity of picture light radiated to a photosensitive material is enhanced at the time of printing the picture of a picture display device to the photosensitive material. SOLUTION: Light radiated by a light source lamp 8 is made incident on a digital micromirror device 10 through a color wheel 9, an integrator 23 and two condenser lenses 21 and 22 at the printing device. The picture light accompanying the picture displayed by the digital micromirror device 10 is radiated to photographic paper 7, and the picture is printed on the photographic paper 7. A filter for uniformity adjustment 24 is provided so as to be close to the exposure surface of the photographic paper 7, and the uniformity of the picture light radiated to the photographic paper 7 is enhanced by the filter for the uniformity adjustment 24.
