<p>In a method for setting a desirable image density by increasing an decreasing the image density in steps by use of a setting key (104, 105) according to the density of original while indicating an image density changed by the setting key by lighting a plurality of indicators (1-7) in steps, an intermediate image density between the steps is set and indicated by switching on an off one of a first indicator which corresponds to an image density set by the setting key when increasing and decreasing the image density to the next step and a second indicator next to the first indicator, or simultaneously lighting or simultaneously switching on and off the first and second indicators.</p> |
