<P>PROBLEM TO BE SOLVED: To provide a color image forming apparatus that is adaptive to high-speed operations resulting from frequent monochromatic image formation. <P>SOLUTION: Image forming stations Pa to Pc where toner images of chromatic colors Y, M, and C are formed are arranged on one surface side of an intermediate transfer belt 4 and an image formation station Pd where a black toner image is formed is arranged on the other surface side of the intermediate transfer belt 4 alone at the lowest downstream from all the image formation stations. Further, the image formation station Pd uses a two-component developer containing a toner and a carrier and a development tank 18d that the image formation station Pd is equipped with has larger storage capacity than that of development tanks 18a to 18c that the image formation stations Pa to Pc are equipped with. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
