PURPOSE:To form a copied picture of different color, by using selectively plural kinds of potoconductive toner which are dyed with different colors. CONSTITUTION:When a switch 10a is turned on to apply a positive voltage to the first toner sticking device 2a, which sticks a red toner, by a bias power source 3, the red toner is stuck to a turning conductive substrate 1 to form a red toner layer. Next, a switch 10b is turned on to operate the second toner sticking device 2b, and a yellow toner layer is formed on the red toner layer. The conductive substrate 1 which is exposed by a light source 4 and has photoconductive toner layers formed is turned continuously, and processes are executed successively. The transfer process is executed when a copy paper S passes between the conductive substrate 1 and a transfer charger 5, and the fixing process is executed by a fixing device 11 provided with a heat roller 6, to obtain an orange copy image. Thus, an optional toner out of photoconductive toners having fundamental colors is mixed to attain rich copy colors. |
