PROBLEM TO BE SOLVED: To generate the image of a process color having an improved color area by the addition of a color area for extending the range of color by utilizing a CAD development system in addition to two DAD developments between second passes. SOLUTION: A photoconductive belt 10 consisting of a photoconductive surface and a conductive base is installed so as to move exceeding over a first CAD(charge area development) development station C, a second CAD development station D, a first DAD(discharge area development) development station E, a second DAD development station F, a third DAD development station I, and the like. A second CAD developer housing structure 66 includes a developer 68 containing a toner particle colored to, for example, orange. A second DAD image formed between second passes is developed between the second passes by the toner of cyanogen included in a second DAD developer housing structure 78. A third DAD housing structure 90 performs the development of a second virtual image. |
