<P>PROBLEM TO BE SOLVED: To provide an image forming device capable of stably performing a secondary transfer of a toner image from an intermediate transfer body to a transfer object body. <P>SOLUTION: The image forming device 100 has; a plurality of image forming means Pa to Pd each of which has an image carrier 1, a developing means 4 and a primary transfer means 5; an intermediate transfer body 7; and a secondary transfer means 8. The image forming device 100 has developer charging means 22a to 22d for charging the developer on the image carriers 1 between developing parts G and primary transfer parts N1 in surface moving directions of image carriers 1 and bias applying means 23a to 23d for applying charging biases to respective developer charging means 22a and 22d, in the plurality of image forming means Pa to Pd, and charging biases applied from bias applying means 23a to 23d to developer charging means 22a to 22d are made different by respective image forming means to make electric charge amounts of the developer on the image carriers 1 different by respective image forming means Pa to Pd. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
