摘要： Photoconductive compositions comprising an organic photoconductive material, an activator capable of forming a charge transfer complex with the photoconductive material, and a protonic acid. Imaging members provided with an imaging layer prepared from the above composition are highly light sensitive, requiring only brief exposure times, and exhibit a photoinduced state of elevated conductivity which persists long after exposure to light is terminated. These compositions can be returned to their relatively insulative state by merely subjecting the imaging layer to heat in the dark, thereby erasing this photoinduced image pattern of elevated conductivity.

摘要： Electrostatographic imaging method employing an imaging member provided with a photoconductive imaging layer containing an organic photoconductive material, an activator capable of forming a charge transfer complex with said material and a protonic acid sensitizer. The acid sensitization of the charge transfer complex in this imaging layer dramatically enhances the photosensitivity of this photoconductive composition and yet avoids the undesirable memory effects generally experienced in such materials when a photoconductive layer of these materials is imaged in accord with the method of this invention.

摘要： A fully integrated electro-optic page-scanner comprises an optically transparent waveguide made from an electro-optic polymer, and an electrode structure including a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. According to the invention, the addressable electrodes are disposed on a photoconductive substrate which facilitates poling of the polymer waveguide to rander it electro-optic in nature. During the poling process, the photoconductive substrate is made electrically conductive by flood illumination, while a uniform electric field is established between the substrate and a transparent electrode which overlies the waveguide layer, opposite the addressable electrodes. Preferably, the photoconductive substrate comprises undoped silicon which enables certain electrode-addressing circuitry to be integrated within the scanner structure.
