質が得られていない。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-recording method and an apparatus using this method, and particularly to a device that controls the adhesion of a powder-solid agent to a conveying member in response to an image-like electric signal, and controls the dispersion of the powder-solid agent. There is a method known as contrastography. In this method, a liquid developer is placed on a recording member and the liquid developer is applied to the recording member using a needle electrode. However, this method using a liquid 'sJLgI agent was impractical because the carrier liquid often permeated into the recording member. On the other hand, in [contrography using a dry developer, a needle electrode is brought into contact with the recording member,
A method of supplying a developing agent from the opposite side of the recording member is known. However, in this case, the resolution is noticeably reduced due to the thickness and conductivity of the KGi recording member, and a sufficiently satisfactory image quality is not obtained.

以下、本発明を実施例に従って詳説する。The present invention achieves the above object by installing a member that deposits a powder developer (hereinafter referred to as toner) and conveys the toner to the lower part of the powder developer (hereinafter referred to as toner). A force is applied to the gate member to prevent it from happening, and a region where the blocking force can be removed in the direction of the toner conveying member is partially formed on the gate member, and as a result, the area on the toner conveying member is This is to form an image based on a pattern of leaked toner. - Hereinafter, the present invention will be explained in detail according to examples.

を通過して流出しない力のバランスにある。In the figure, reference numeral 1 denotes a cylindrical toner conveying member, which is composed of a conductive non-magnetic cylindrical member 1b having an insulating thin layer 1a on its surface, and rotates in the direction of the arrow. This conveying member 1 has a fixed magnet 2 inside it. Conductive magnetic toner 4 is stored in a toner container 6 in which it is deposited. The gate member 5 that controls the outflow of toner from the toner container is made by adhering a large number of electrodes 8 independently extending over the entire width of the toner transport member to a magnetic or non-magnetic support 6 via an insulating layer 7. The electrodes 8 are each connected to a signal generation source 9 and made of a magnetic material. On the other hand, the fixed magnet 2 inside the toner transport member is provided with a magnetic pole facing the gate member 5, and a strong magnetic field is formed between it and the electrode 8, which is particularly made of a magnetic material. Even when the toner conveying member 1 rotates, the toner 4 is constrained by the magnetic field and has a force balance that prevents it from flowing out through the gate member.

れて利用される。With the above configuration, when a controlled voltage is applied to the electrode 8 from the electric signal generation source 9, a current flows from the electrode 8 through the conductive magnetic toner, and the toner and the conductive cylinder 1b are sandwiched between the insulating layer of the toner transport member. Electrostatic attraction is applied to the toner, which overcomes the restriction of toner outflow due to the magnetic field at the gate member position, selectively releases Ktlt onto the surface of the toner transport member 1 [by adhering to this toner transport member] Gu Gawei is formed on the surface. The thickness of the insulating layer 1b on the toner transport member 1 is preferably several microns or less, because the thinner the insulating layer 1b, the stronger the electrostatic attraction will act even if the voltage applied to the electrode 8 is low. Further, since this toner conveyance S# is used repeatedly, it is desirable that the toner charge K is discharged within one rotation and that no accumulation of charged charges occurs. Furthermore, since the material used for the toner conveying member constantly rubs against the toner, it is effective to use a material with low surface energy so that the frictional resistance with the toner is small and slippage is likely to occur. The toner image formed on the toner conveying member 1 is transferred and fixed onto another recording member 11 such as a transfer paper by an electric field applying means of a suitable corona discharger 10 and used.

る・ことができる。Furthermore, by making the part of the toner container 6 close to the toner conveying member magnetic, and arranging the magnetic pole at a position facing that part of the fixed magnet 2, it is possible to prevent the magnetic toner from flowing out of the toner container and at the same time to remove the remaining toner. It can also be used to clean the statue.

のは、同一の付号を付しである。However, in the present invention, it is necessary to prevent toner from flowing out from the gate member except during image formation.
For this purpose, the shape of the constraining magnetic field at the gate member position M is essential. FIG. 2 is a sectional view of the gate member portion showing an example of the @pole arrangement where toner is difficult to flow out at the gate member position. Note that components having the same functions as those shown in FIG. 1 are given the same reference numbers.

With respect to the magnetic pole of No. 2, an electrode 8 made of a magnetic material is disposed so as to be shifted from the position facing directly to the side where the toner is detected.

搬送部材との間を満すことができなくなる。When the lines of magnetic force 13 indicated by broken lines are in the direction shown in the figure, toner passage is effectively blocked. In this way, the more oblique the counter one-way Knm field is to the direction of movement of the toner conveying member, the more completely the toner passage is blocked. However, because a toner chain is generated along the magnetic field, current tends to flow through this chain when voltage is applied to the electrodes, so if the toner chain is too slanted, the force will decrease. ,
It becomes necessary to temporarily increase the voltage applied to the electrode 8. Furthermore, if the magnetic field becomes too oblique, toner movement occurs and the toner is removed from between the gate member and the conveyance member for recording by voltage application, and then the toner fills this gap. This makes it impossible to quickly fill the gap between the gate member and the toner conveying member.

４５’の範囲に選択することが好ましい。Taking these constraints into consideration, the inclination of this magnetic field, that is, the angle formed by the direction of the magnetic field with respect to a line perpendicular to the surface of the toner conveying member, is approximately 0 to 60 degrees, especially 1/C5 degrees to 0 degrees.
It is preferable to select a range of 45'.

。In the above embodiment, a case was described in which conductive magnetic toner was used, but it is also possible to form an image on the toner conveying member in the same way even if insulating magnetic toner is used. However, in this case,
Generally speaking, the voltage applied to the electrode 8 required for recording is higher than when using conductive magnetic toner, and the toner is easily charged and its mirror image force causes the toner to adhere to the toner conveying member. The disadvantage is that it tends to cause fogging.

である。As a means to prevent this fogging phenomenon, it is possible to coat the toner conveying member with a substance that is charged to the same polarity as the toner generated by frictional charging. The shape of the entrance gate member may also be modified, and a method is required to prevent the toner from solidifying (blocking) in the toner container. For example, it is also possible to form the support body 6 of the tJ member with a magnetic material to increase the toner bundling and binding force by the gate member.
