ABSTRACT:
A CPU computes a saturation moisture content on the basis of a temperature and a relative humidity detected by environment detection means, and multiplies the saturation moisture content by a square of the relative humidity, thus obtaining an environment parameter value. The CPU sets a proper development contrast potential using the environment parameter value according to a correlative approximation expression with pre-calculated development contrast potentials.
