    • A color picture image formation device includes a plurality of photosensitive body drums and a plurality of image formation sections each consisting of a charge unit, an exposure unit and a plurality of developing units for developing toner picture images of various colors and an intermediate transfer body for holding the toner powder images of required number of colors, which transfers the toner picture images to the recording paper and fixes them thereon by a fixing unit after all the toner picture images have been formed on the intermediate transfer body. A transfer voltage is applied by the intermediate transfer body for every developing unit. The intermediate transfer body is a drum formed as a multiple layer structure including a metallic tube, an insulation layer, a metallic conductive electrode which is split into a plurality of sections, and a voltage application layer on the surface of the metallic tube. A transfer roller transfers the toner-picture images onto the recording paper. A voltage application brush which comes into contact with the sections of the metallic conductive electrode applies voltage to the intermediate transfer body.

    • Provided is a drive control device capable of surely detecting, by a monitoring/controlling unit, an abnormality of a short circuit and a disconnection in a power supply circuit to an electric load, and of decreasing a load required for a quick response imposed on the monitoring/controlling unit. A switching element is controlled to open/close by a control output signal generated by a monitoring/controlling unit, and a determination storing circuit determines whether circuit opening and circuit closing have been correctly carried out and stores a result of the determination, and periodically reports to the monitoring/controlling unit. While the stored content of the determination is periodically reset, the determination operation is updated and continues. The monitoring/controlling unit does not need to immediately monitor the determination storing signal when the open/closing command is generated.

    • An electrostatic recording apparatus is provided which comprises a recording electrode with a plurality of stylus electrodes and a developing device with a back electrode provided on opposite sides of a recording medium. The recording apparatus is capable of simultaneously processing the forming of and development of a latent image by using the recording electrode which has a magnetic piece embedded at a tip portion thereof. A magnetic field is concentrated in its path and is increased in a narrow gap region between the recording electrode and the back electrode. Toner chains of magnetic particles in the developing process can easily stand upright on the back electrode, and can thus easily and uniformly contact the recording medium. Dot defects on a formed image, are therefore, avoided. The present invention is directed to several embodiments of the magnetic piece and the manner of embedding the magnetic piece in the recording electrode.
    • 提供了一种静电记录装置,其包括具有多个触针电极的记录电极和在记录介质的相对侧设置有背电极的显影装置。 记录装置能够通过使用具有嵌入在其尖端部分的磁性片的记录电极来同时处理潜像的形成和显影。 磁场集中在其路径上并且在记录电极和背电极之间的窄间隙区域中增加。 显影过程中的磁性颗粒的调色剂链可以容易地直立在背面电极上,并且因此可以容易且均匀地接触记录介质。 因此,避免形成图像上的点缺陷。 本发明涉及磁片的几个实施例以及将磁片嵌入记录电极的方式。
