FIG. 1 is a side view of essential parts of an embodiment of the device of the present invention, and FIGS. 2 and 3 show the transfer order of each color toner image in a conventional full-color device, and the transfer discharge voltage and transfer rate at that time. Figures 4, 6, and 7 show the relationships between the two under different conditions, respectively, showing the transfer order, transfer discharge voltage, and transfer order of each color toner image when using the device of the present invention. Figure 5 shows the relationship with the rate when operating under different conditions.
The figure shows that the purpose and effect cannot be achieved if other pretreatment conditions are applied, and FIG. 8 is a side view of the main parts of a conventionally known full-color copying machine. 1...
