PURPOSE: To obtain a reproduced image with high reproducibility even when printing is performed by exposing photographic film for a long time and printing is performed in large enlargement ratio from the photographic film.

CONSTITUTION: A curling preventing filter 66 is formed so that transmissivity may be about 90% in the wavelength band of visible light, it may be reduced as the wavelength becomes longer in the case of exceeding the visible wavelength band, it may be about 50% or ≤50% when the wavelength is 1200nm, and it may be about 10% or ≤10% when the wavelength is 1500nm. By arranging the curling preventing filter 66 to an infrared cutting filter 64 which transmits the visible light and shields the light to about 1200nm, the light whose wavelength is ≥ about 1200nm is dimmed and the energy corresponding to the light whose wavelength is ≥ about 1200nm out of the energy of the light irradiating negative film is lowered. Thus, the negative film is prevented from curling and the divergence of focus is not caused.
