The above purpose'I! - Achieved by the present invention, there is provided a toner support which holds a powdered -component developer on its surface by a force such as a magnetic field or electrostatic force; a recording member disposed at a certain distance from the support; A control member is provided between the recording member and the toner support for controlling the passage of the toner agent. The control member has an aperture through which toner passes and has first and second electrodes facing each other, one electrode being applied with a predetermined reference potential;
The other electrode has an insulated signal electrode corresponding to each aperture. The passage of toner by the control member is controlled by applying an alternating voltage between the toner support and the control member, and applying a voltage between the recording member and the control member in the direction of guiding the toner to the recording member. Furthermore, by selectively applying a voltage to the signal electrodes of the control member, an electric field is generated within the aperture of the control member to control the passage of toner and guide it to the toner recording member. In the above configuration, toner may reach the control member and block the opening, which may interfere with subsequent control.To solve this problem, if the control member does not control the passage of toner, the control member An electric field is created between the toner and the support that attracts the toner toward the support. At this time, preferably, the electric field between the arrangement member and the control member may be eliminated. Alternatively, by forming an electric field in the direction of returning the toner to the support within the opening of the control member, it becomes possible to return the toner that blocks the opening to the toner support and use it again.

FIG. 2 is a cross-sectional view of an apparatus showing an embodiment for explaining the basic operation of the apparatus using the control member as described above. In the figure,
1 is a signal electrode to which an image-like signal voltage is applied, and 3 is a reference electrode which is usually electrically grounded. 2 is an insulating member that makes the signal electrode 1 and the reference electrode 3 face each other and electrically insulates them. Furthermore, 4 is an opening that passes through the signal electrode 1, the reference electrode 3, and the insulating member 2. 5 is a back electrode for applying a voltage to the recording member; 6 is a recording member that is brought into close contact with the back electrode 5 and moved in the direction of the arrow; 07 is a thin layer of toner that is conveyed to the recording section located at the position of the opening 4; The toner 9 in the toner container 8 is a one-component magnetic toner and is fixed inside the toner conveying member 10, which is rotated in the direction of the arrow, by a toner conveying member 10, which is a non-magnetic cylinder, and is alternately distributed in different directions. Due to the action of the magnet 110 with alternately magnetized magnetic poles,
When the toner conveying member 10 rotates in the direction of the arrow K11, the toner 9 conveyed by the action of the doctor blade 120 on the toner support becomes a uniform thin layer. Due to the action of the alternating current electric field supplied to the toner transport member 3 and the toner transport member 10, a force reciprocating between the electrodes is generated, as if a toner cloud was formed. 16 is a direct current that connects the reference electrode 3 and the back electrode 5.
At this time, when a voltage is applied from the signal power source 15 to the signal electrode 1, the toner 9 is applied to the signal electrode 1, and the toner 9 is controlled by the signal electrode IK and transferred to the signal electrode L. The toner 9 that has progressed and passed through the apertures is further accelerated and reaches the recording member 6 to form an image.

In the device with the above configuration, when the signal voltage is repeatedly applied from the signal power supply 15 to the signal voltage lil, the toner 9 flows inside the aperture 4 at the moment when there is no signal between each note, and as a result, the aperture 4 A possible solution to this problem is to superimpose a DC component on the AC voltage output from the AC power supply 14. According to this method, the toner 9 cannot sufficiently reach the apertures 4, resulting in low image density, and in order to control the toner 9, it is necessary to increase the signal voltage to the signal electrode 1, so a signal power source with high voltage output is required. Not only that, spark discharge occurs between the reference electrode and the signal electrode, so this is not necessarily an optimal solution. Figure 3 shows the recording position to explain the behavior of the toner 9 at the control position in the apparatus shown in Figure 1 above. 13 is an enlarged cross-sectional view of a part of FIG.

In the figure, the gap between the back electrode 6 and the control electrode 10 can be in the range of 100 microns to 10 m, and in this embodiment it is about 300 microns, and the gap between the back electrode 5 and the reference electrode 3 is approximately 300 microns.
A DC voltage of 300 V is applied from a DC power supply 16 between the zero reference electrode 3 and the toner transport member 10, and an AC voltage I KV, 4.5K is applied by an AC power supply 14.
H2 is applied, and the distance between both members is set to 600 microns, but the frequency of the voltage 9 changes depending on the gap distance. The control electrode 1 and reference electrode 3 are kept at a gap of 35 t microns by the insulating member 2. , and a signal voltage of 180 V necessary for image formation is applied from the signal power source 15. Then, as described above, the reference electrode 3, the control electrode 1, and the insulating member 2
An opening 4 having a diameter of 150 microns is provided through which the toner 9 passes, and the average diameter of the toner 9 is about 13 microns.

The waveform from the AC power supply is shown as 4Ab. On the other hand, FIG. As explained in Figure 3, when there is no input signal, the opening 4
The waveform diagram of Figure 4 shows that the toner 9 may stain the toner. On the other hand, Fig. 4B is a waveform diagram to solve this problem. Fig. 4B shows that even if the toner 9 stays on the wall of the aperture 4 or the reference electrode when there is no input signal, , shows a state in which a DC voltage having a polarity opposite to that of the toner that attracts the staying toner 9 to the toner conveying member IO is superimposed on the AC voltage for clouding the toner at a portion d where there is no human input signal. That is, according to this embodiment, when there is no signal, the voltage changes so that the toner conveying member has the opposite polarity to the toner, so that the toner near the openings can be returned to the conveying member. In the configuration shown in FIG. 2, while the AC voltage vp-p is I KV, by superimposing a DC voltage of +400 Vi 1 degree on this AC power supply 14, the aforementioned negative polarity staying toner 9 can be removed. Not only is it possible, but the reference electrode 3
It is possible to remove even the toner that adheres to the 0 surface, and the opening 4

In the above configuration, the same result can be obtained by controlling the AC power supply 14 when there is no signal voltage to the signal electrode 1 and superimposing the DC voltage on the AC voltage.Of course, if the toner is of positive polarity, The DC voltage superimposed on the AC voltage has negative polarity. Figure 5 shows a diaphragm showing another embodiment. In the case of this embodiment, when there is no input signal, only the DC voltage component is applied to the conveying member, and the effect is the same as the embodiment shown in FIG. 4B. 5b in waveform
As explained above, when there is no input signal, a DC voltage with the opposite polarity to the toner is superimposed on the AC component to the toner transporting member, or a DC voltage with the opposite polarity to the toner is used. By applying a DC voltage of 1, the opening is not blocked by toner, and the accumulation of toner on the reference electrode is not only eliminated, but also unnecessary scattering of toner is reduced, and image stains are also reduced. This enabled stable image formation over a long period of time.

In addition, although magnetic toner was used as the toner in the above example,
When the toner conveying member supports the toner by electrostatic force, flocking, or the like rather than by a magnetic field, the toner is not limited to magnetism, but may be any toner having a constant polarity potential. Further, regarding the application of AC voltage to the conveying member, it is also possible to change to DC voltage synchronized with the signal voltage, since the toner can be transferred to the control member when necessary.
