Patent abstract
An exposure system is provided with an exposure head formed of a red organic EL element which emits light in a red region and another organic EL element which emits light in a predetermined wavelength range shorter than the red region. The exposure system exposes a color photosensitive body containing therein at least a red silver-salt photosensitive material sensitive to the light in the red region and another silver-salt photosensitive material sensitive to the light in the predetermined wavelength range. An optical filter cuts the wavelength components which are shorter than the predetermined wavelength range and included in a sensitive range of the red silver-salt photosensitive material.
