1. In an image forming method wherein a light-sensitive material having spectral sensitivity characteristics with a peak value is exposed under a semiconductor light source, the improvement comprising:

  • rendering a center wavelength of variations in peak spectral radiation due to variation of temperature from said light source substantially equal to a wavelength for peak spectral sensitivity of said light-sensitive material, and compensating any temperature-dependent variations in said radiation intensity of said light source.
