しないときは帯電器２は必ずしも必要ではな゛い。In the present invention, an electrostatic latent image created by an electrophotographic method or an electrostatic recording method is developed with developing particles containing sensitive particles sensitive to each wavelength, and then This is a method of obtaining a color image by exposing to different lights, and here we will explain a method using electrophotography as an example. Therefore, when using the electrostatic recording method, an electrostatic recording medium may be used in place of the electrophotographic photoreceptor 1, and an electrostatic recording head may be used in place of the image exposure optical system unit 3-1. In this case, the charger 2 only needs to have the function of maintaining a constant potential on the electrostatic recording medium, but the charger 2 is not necessarily required when the electrostatic recording medium is not used repeatedly.

の帯電極性側に現像バイアスをシフトさせて現像する。First, the surface of the electrophotographic photoreceptor 1 is charged to a constant potential with the charger 2, and the surface of the electrophotographic photoreceptor 1 is imagewise charged with the image exposure optical system unit 3-1 (here, the laser scanning optical system unit). Chargeable developer particles 41 charged to the same polarity as the charging polarity of the electrophotographic photoreceptor 1 are attached to the surface of the electrophotographic photoreceptor 1 in the area where the potential is attenuated by the exposure, and are developed by the developer 4. To achieve this, as shown in FIG. By rotating the developing roller 42, which has been brought into pressure contact (avoiding the edges) and whose surface has been roughened to a roughness equal to or less than the number average particle diameter of the developed particles 41, in the direction of the arrow shown, the layer of developed particles 41 is thickened. It is formed on the developing roller 42 with a thickness of about 120 μm. Further, in order to develop the developing particles charged with the same polarity by adhering to the area where the potential of the electrophotographic photoreceptor 1 is attenuated, the developing roller 42 is moved against the back electrode of the electrophotographic photoreceptor 1.
Developing is performed by shifting the developing bias toward the charging polarity side.

For example, when applying a DC voltage, a voltage that is approximately equal to or lower than the charging voltage of the electrophotographic photoreceptor 1 may be applied, and when applying an alternating voltage, an AC voltage with a frequency of 400 Hz to 3 kHz and a vpp of approximately 5 oovpp2KVpp may be applied to the DC voltage. .

る。The present invention reduces the number of repeated steps, making it possible to minimize problems such as ozone generation and image shift. Further, even when reproducing a color separation image by digital processing, there is no need for a page memory or a buffer memory for storing the color separation image for each color. Furthermore, since developers and devices for different colors are not required, the entire device can be made smaller. Furthermore, unlike the conventional color dry silver method, consumable materials are used only in the image area, so it is also economical.
