By stacking them and passing them through a heated roll fixing device, it is possible to use plain paper as transfer paper, and by creating a multicolor toner image on a dielectric film, the problem of color misregistration has been solved. This is what I did.

FIG. 1 is an explanatory diagram of the formation of a multicolor toner image on a dielectric material according to the present invention. A needle-shaped recording electrode 2 is placed on one side of the dielectric sheet 1, and a conductive toner layer 4 formed on a ground plate 3 is placed on the other side. Here, when a voltage is applied to the recording electrode 2 by the power source 5, charges of opposite polarity to the applied voltage are induced from the grounding plate 3 to the toner 4a in contact with the dielectric sheet 1 of the conductive toner layer 4. The charge from the recording electrode 2 and the charge on the toner 4a are attracted to each other by Coulomb force,
The toner 4a adheres to the dielectric sheet 1 and is visualized.

In the case of multicolor, the same operation is repeated, but in conventional multicolor electrophotography, the toner image formed by the first development is disturbed by the second development, and powder development Multicolor recording was difficult. Conventionally, for example, a toner image resulting from first development is transferred onto a transfer paper, then second development is performed, and the image is transferred again, which often results in color misregistration.

In the case of the conductive toner of the present invention, as shown in FIG. 2, the amount of charge obtained from the capacitance of the dielectric sheet 1 and the applied voltage is all induced into the toner 4a, and is not supplied during the second development. toner 4
No charge is induced in the toner 4, and the toner 4 does not adhere to the dielectric sheet 1 due to the first afterimage/charge. Therefore, according to the present invention, a multicolor toner image without any disturbance can be formed on the dielectric sheet 1.

In multi-color development, it is better to have the same polarity of charge applied to the dielectric film during the first development and the second development to prevent aggregation, etc. between the first toner and the second toner. Good image quality is obtained with no interaction.

As a developing method, an imprint method using conductive toner may be used, but a method in which toner beads are made using magnetic toner to form conductive paths provides a sharper image. At this time, it has been experimentally found that the sharpness increases when an alternating electric field is superimposed on a DC voltage as the voltage applied between the sleeve and the recording electrode on the dielectric material. Although the reason for this is not certain, it is thought that a sharper image can be obtained by breaking the agglomeration of toner particles due to interactions between toner beads and vibrations within toner beads.

In order to solve this problem, the present invention uses a method in which a dielectric film on which an image has been formed and transfer paper are stacked and passed through a hot roll fixing device, thereby transferring and melting the toner and fixing it onto plain paper. At this time, in order to transfer the toner onto the dielectric film, the critical surface tension of the dielectric film must be lower than that of the toner. Furthermore, the dielectric film must have good heat resistance since the temperature reaches approximately 190°C during transfer and fixing. As a dielectric film that satisfies the above conditions, fluorine-based films such as polyimide film, Teflon, and PVDF are suitable. In fact, according to this embodiment using this method, any type of transfer paper including plain paper can be transferred. In addition, transfer of trap pens, second base paper, etc. could be performed well, and the transfer performance was also good, with a transfer rate of nearly 100%.
