Pixel Image Formation on a Multi-Layered Organic Film Installed with Pixel-Like Floating Electrodes

摘要

We have proposed a novel capacitor-controlled imaging device consisting of an insulator installed with pixel-like middle floating electrodes on a metal substrate. In this device, the corona charged surface potential can be reduced to the value calculated from the capacity of an insulator above the floating electrode by connecting the floating electrode to ground potential. In this work, by replacing the bottom insulator with organic photoreceptor (OPC), the light addressing was examined for grounding the floating electrodes through photoconduction in the OPC layer. The surface potential of the whole area just above the floating electrode was successfully controlled by light irradiation, even when the light was focused to the area smaller than the floating electrode. This result allows us to construct the digital dot image on the photoreceptor installed with the pixel-type floating electrode array in the future.
