Источники информации, прин тые во внимание при экспертизе: 1. Патент США № 3430606, кл. US-637, 1Э69.In the upper part of the housing there is an inlet 13 with a cone 14, and in the lower part an outlet 15 and a tube 16, the end of which is located above the lower 17 of the developing unit. Electrically conducting plates with a reversing switch are connected by means of wires 8 and 19. A device for controlling the concentration of corrosive particles works as follows. An electrical potential of a corresponding polarity of a predetermined magnitude is alternately applied to the 2 to 3 electroconductive plates to attract and hold the particles of the curve of one plate and repel the particles of another. Regarding the location of the photocell 8 and the source of illumination 7, such that the photocell receives light rays from the source of illumination, the developer passes black between the electrically conductive plates 2 and 3 and settled in a turn on one of the electrically conductive plates, and then on the other of each cycle, "Attack -" repulsion ("cleaning). The source of the light is connected to the current source so that it gives light during the measurement process. The adjustment for: Leler is carried out by continuously measuring the number of bends pressed on both electrically conductive plates 2 and 3 during multiple cycles of "attraction and" repulsion. With amer, in the first half of the cycle, each of the plates 2 and 3 attracts bend particles, and in the second half of the cycle, each of them repels charge particles. "Cleaning can be done if the plate that does not fit" is attractive, and has a repulsive field for a negative turn, which is determined by the potential difference between the two levels. The invention The device l, l coggrol concentration of turn-off particles in an electrophotographic developer, containing a source of electric current, two electrically conducting plates installed with a gap, electrically connected by a switch with a current source, a tray for directing the flow of the developer between plates and a photoelectric recording system, including a light source mounted behind one of the plates, and a photoelectric element, characterized in that, in order to improve the control of the concentration of angular particles n {) o wittel, electrically conductive plastic; are installed parallel to each other and are connected to different zeroes of the current source, while the photocell of the recording system is mounted behind another plate, and the switch is reversible.
