摘要： PROBLEM TO BE SOLVED: To provide a carrier liquid recycling apparatus which extracts a carrier liquid with high purity from a recovered carrier liquid, and continuously treats a sufficient amount with respect to a throughput.
SOLUTION: In the carrier liquid recycling apparatus, the recovered carrier liquid is poured from a filling port 6 while rotating an electrically conductive roller 2 in the state where bias voltage is applied to an electrically conductive pipe 1. Since an electric field based on the bias voltage is applied with the rotation of the electrically conductive roller 2 in a radial direction along a comparatively long route, a toner solid content in the carrier liquid sufficiently adheres to the surface side of the electrically conductive roller. As a result, the pure carrier liquid is extracted from a discharge port 7. A blade 4 has sufficient elasticity to collect the carrier liquid while passing a toner solid content deposited on the surface side of the electrically conductive roller 2. The deposited toner solid content is scraped and recovered by a recovering blade 3.

摘要： PROBLEM TO BE SOLVED: To provide an information input device that can stably read out IC information.SOLUTION: An information input device 1 includes a fluctuation mitigation member for mitigating fluctuation in magnetic field intensity due to an installation surface. The fluctuation mitigation member is a bottom face sheet plate 50, made up of a metal member, and made of, for example, stainless steel, aluminum, copper, or iron. The bottom face sheet plate 50 mitigates influence from the installation surface by making it larger than the outer circumference of an antenna 20, and the information input device 1 can stably perform radio communication with an IC chip. Therefore, the bottom surface sheet plate 50 should not be performed large drilling in a projected area of the antenna 20 when it is viewed from vertical upward and is performed drilling outside of the projected area of the antenna 20.

摘要： PROBLEM TO BE SOLVED: To provide a technology for measuring surface potential at low cost to stabilize charging potential and to improve image quality, without using a 'surface potential sensor' or an 'AC biased power supply' causing high cost. SOLUTION: A known image pattern is formed with a means such as exposure on a photoreceptor, a current value corresponding to the pattern is measured, and surface potential is measured. Specifically, a bias is applied to a development roller and current which flows into the development roller from the photoreceptor is measured. Accordingly, an inexpensive high-performance image can be obtained by feeding back the measured surface potential to electrification control of the photoreceptor. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To achieve, in a mechanism for recycling liquid toner unused in the developing process of a liquid development electrophotographic device using the liquid toner, a liquid toner recycling device having a concentration recovery mode that prevents a liquid overflow resulting from concentration adjustment even when images using a large amount of toner solid content are consecutively printed. SOLUTION: As shown in Fig. 1, the toner recycling device has devices which are provided for a developing roller 1 and a photoreceptor 2 in order to recover residual toner. When toner concentration in a toner concentration adjustment tank for concentration adjustment has decreased, a concentration recovering operation is started. As illustrated in Fig. 1, the charging potential of the photoreceptor body and the force of an electric field generated by the charges of the toner solid content are caused to repel each other, thereby causing only carrier oil to move onto the photoreceptor body. Thus, the concentration of the recovered toner is increased, and this is used for adjusting concentration in the toner concentration adjustment tank. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To obtain a developing mechanism for a liquid developing electrophotographic device equipped with constitution where an image is transferred and supplied from a photoreceptor to a roller type intermediate transfer body, and preventing trouble that liquid toner remaining on the surface of the photoreceptor provided in the developing mechanism stains a printing medium when the developing mechanism does not transfer and supply the image to the intermediate transfer body. SOLUTION: The developing mechanism for the liquid developing electrophotographic device is equipped with a mechanism for linearly retreating and also turnably retreating the photoreceptor from a position where it comes into contact with the intermediate transfer body when the developing mechanism stops developing operation. At the time of stopping development, the photoreceptor is turnably retreated so as to guide residual toner remaining on the surface of the photoreceptor in a direction where it goes away from the intermediate transfer body.
