    摘要： An array of light emitting elements comprises an insulating substrate, a dot anode array including a multitude of dot anodes defined by conductors and phosphors formed on the substrate, a thermionic emission cathode disposed in opposing relationship with the dot anode array, and a grid interposed between the cathode and the dot anode array. An accelerating electric field is selectively established between the dot anodes and the cathode to excite the phosphors on the dot anodes with low speed electron beams, thus causing the phosphors to emit light. The array is primarily used in an electrophotographic printer.

    摘要： In an electrophotographic photosensitive device including a conductive layer, a selenium based photoconductive layer and a transparent insulating layer which are sequentially laminated, the conductive layer is formed of an aluminum substrate conductive layer, a zinc conductive layer a copper conductive layer, and silver conductive layer which are sequentially laminated to each other. As a result of this structure, the charge injection characteristic of the photosensitive device during primary charging is improved, and the charge injection preventing characteristic during the simultaneous secondary charging and image exposure steps is sufficiently maintained. The conductive layers contact each other intimately. The electrophotographic photosensitive device is highly humidity durable and exhibits a long life and can obtain high electrostatic contrast.

    摘要： A photosensitive member for electrophotography basically comprises a conductive support, on the surface of which a photoconductive layer and a transparent insulating layer are sequentially laminated. The photosensitive member is adapted to be used in a process for forming an electrostatic latent image including sequential steps of a primary corona charging concurrent with imagewise exposure, a secondary corona charging and a flush irradiation. The surface of the conductive support is treated to a mirror finish, based on experimental finding that the contrast voltage of the latent image depends on the degree of surface roughness of the support.

    摘要： In an electrophotographic photosensitive device including a conductive layer, a selenium based photoconductive layer and a transparent insulating layer which are sequentially laminated, the conductive layer is formed by an aluminum substrate conductive layer, a zinc conductive layer (or a zinc conductive layer and a copper conductive layer), and a nickel conductive layer which are sequentially laminated to each other. As a result of this structure, the charge injection characteristic during the primary charging step is improved, and the charge injection preventing characteristic during the simultaneous secondary charging and image exposure steps is sufficiently maintained. The conductive layers contact each other intimately. The electrophotographic photosensitive device exhibits a high humidity durability and a long life and can obtain high electrostatic contrast.

    摘要： An electrophotographic process and apparatus for performing the process which employs an electrophotographic photosensitive member of a basic construction in which a photoconductive layer and a transparent insulator layer are sequentially laminated on the surface of a conductive supporter. The process comprises a first step of providing a primary charge uniformly from the surface side of the transparent insulator layer, a second step of performing a secondary corona charging during an imagewise exposure by applying a square wave voltage whose voltage-time integration value of a polarity reverse to the primary charge is larger than that of the same polarity thereas and a third step of forming an electrostatic latent image on the surface of the transparent insulator layer by applying a uniform exposure.
