<P>PROBLEM TO BE SOLVED: To provide an image forming device that prevents carrier deposition to be caused by correcting the density of one developing unit to conform to that of the other developing unit when the density of the one developing unit changes, or prevents hue of a multiple-order color from being changed when rates of change in density are different by color. <P>SOLUTION: The image forming device having a plurality of developing devices 4 for developing an electrostatic latent image on a photoreceptor drum 1 as a toner image by use of developers of multiple colors, includes a density sensor 500 detecting the amount of toner of the toner image for each color. When the density sensor 500 detects that the amount of toner of any color is beyond a predetermined range, a developing condition of the other developing devices 4 than the corresponding developing device 4 is changed so that the images developed in the developing devices 4 have the same density. <P>COPYRIGHT: (C)2012,JPO&INPIT |
