Abstract
There is disclosed an image-forming method, which comprises: subjecting a color light-sensitive material to exposure, by using, at least, a first, second, and third light-emitting element whose peak wavelength of the light-emission spectrum is in a first wavelength region of 380 to 500 nm, a second wavelength region of 500 to 600 nm, and a third wavelength region of 600 to 740 nm, respectively, and subjecting the exposed color light-sensitive material to development processing, wherein the color light-sensitive material has, at least, spectral sensitivities in the from first to third wavelength regions. There is also disclosed organic light-emitting elements for use as light sources for exposure in the method. According to the method, digital color images exhibiting good color reproduction can be obtained by exposing a light-sensitive material according to image information and carrying out development processing.
