Abstract
In an ink-jet recording apparatus, when an intensity of the energy of electromagnetic waves of a predetermined region is E and an optical density of the image recorded on a recording medium based on an image signal is D, a controller conducts the image recording such that a characteristic curve representing a change of the optical density D for a logarithm of the energy intensity E becomes a monotone increasing function or a monotone decreasing function. When &ggr; , &ggr; and &ggr; are defined on the characteristic curve such that an inclination of a line connecting points corresponding to E and E is &ggr; , an inclination of a line connecting points corresponding to E and E is &ggr; , and an inclination of a line connecting points corresponding to E and E is &ggr; , the characteristic curve is determined so as to satisfy the following formulas: |&ggr; |<|&ggr; | and |&ggr; |<|&ggr; |. The image recording for the energy intensity E between E and E is conducted based on &ggr; , the image recording for the energy intensity E between E and E is conducted based on &ggr; , and the image recording for the energy intensity E between E and E is conducted based on &ggr; .
