。EXAMPLES Hereinafter, the charge distribution sheet of the present invention will be described with reference to the drawings. FIG. 1(a) is a charge distribution sheet of the present invention, and FIG. 1(b) is a diagram showing the principle of a method for placing charges on the surface using the sheet. In FIG. 1(a), 101 is an insulating sheet-like support. A conductive layer 102 is provided on the front surface, and a conductive back electrode 103 is provided on the back side. The usage will be explained with reference to FIG. 1(b). A needle electrode 104 and a ground roller 10 are attached to the conductive layer 102 of this sheet.
6 are brought into contact with each other and a voltage is applied from the electric signal source 105 to partially remove the conductive layer 102 due to discharge breakdown. 110
is that portion, and 111 is the remaining conductive layer. Move the electrification distribution sheet in the direction of the arrow and attach the conductive back electrode 1.
03, a back electrode voltage application roller 10 connected to a power source 108
7 is brought into contact to maintain its potential, and a grounded conductive brush is brought into contact with the surface. Through such a process, the potential of the conductive portion becomes the ground potential, and the portion from which the conductive layer is removed becomes a potential close to the potential of the back electrode. That is, charges can be distributed in each portion in the same pattern as the conductive layer pattern.

ことができる。After the electric charge is distributed in this way, the charged toner can be brought into contact with the insulating portion from which the conductive layer has been removed in the same manner as in a normal electrophotographic process, and the toner can be attached to the insulating portion from which the conductive layer has been removed. Printed matter can be obtained by transferring and fixing this toner onto paper or the like using a well-known electrophotographic process.

い静電コントラストを得ることができる。By appropriately adjusting the potential of the conductive back electrode 103 and the conductive brush, it is possible to place charges suitable for subsequent processes (for example, toner development) on the conductive layer portion and insulating portion on the surface of the charge distribution sheet. can. When the charge distribution on the charge distribution sheet is used as a latent image in electrophotographic printing, high electrostatic contrast can be obtained since it is not limited by the withstand voltage of the photoreceptor.
この説明においては、導電層の除去は放電破壊で行った
が、当然これに限られないことは明らかである。例えば
、機械的に表面の導電性を削り取ってしまうという方法
もある。In this explanation, the conductive layer is removed by discharge destruction, but it is obvious that this is not limited to this. For example, there is a method of mechanically scraping away the conductivity on the surface.

着色塗布層にすると、表面からパターン状の導電層がは
っきりと見え、何かと使いやすい。A plastic sheet is most suitable for the insulating sheet support. Vapor-deposited aluminum is easy to make and can be uniformly conductive. The conductive back electrode may be deposited by vapor deposition, but if it is a colored conductive coating layer containing carbon or tin oxide and a color pigment, the patterned conductive layer will be clearly visible from the surface, making it easier to use.
放電破壊で導電層を取り除く場合は、絶縁性のシート上

ンが作れる。When removing a conductive layer due to discharge breakdown, providing a roughened layer on an insulating sheet stabilizes the discharge phenomenon and allows delicate patterns to be created.

写が行なわれない。When using this charge distribution sheet in an electrophotographic process, it may be preferable to partially insulate the conductive back electrode instead of forming it into a uniform layer or coating. for example,
When transferring toner to paper or the like, if the back electrode remains at a high potential, the attraction force to the toner will be strong and the toner will not be sufficiently transferred to the paper.

うとして電圧を上げたい場合には、裏電極はシート端部
までない方が良い。In such a case, if the back electrode is partially insulated, it is possible to apply opposite voltages during the development process and the transfer process to assist in toner transfer. Further, at the edges of the sheet, the conductive layer and the back electrode are close to each other at the end surface of the sheet, and the dielectric strength inevitably becomes weaker. If you want to increase the voltage by loading a lot of charge, it is better not to have the back electrode all the way to the edge of the sheet.

Crosslinking agent (Crispan Dainippon Ink & Chemicals Co., Ltd.)
1 part by weight of the paint was applied so that the dry coating amount was 4 g/rd, a roughened layer was formed, and aluminum was applied on the top and back of this roughened layer to a thickness of 600 g/rd. A charge distribution sheet was created by vacuum deposition. This charge distribution sheet was printed using a commercially available discharge printer (UA72.OK, manufactured by Nippon Aleph). -I on the back electrode of this sheet
The surface was rubbed with a grounded conductive brush applied with a potential of K■. Thereafter, when development was performed using a developing device used in an electrophotographic process, toner was thickly adhered to the areas where aluminum had been removed due to discharge breakdown. A small amount of toner was attached to the conductive layer. Good results were obtained when a bias voltage of -300V was applied to the sleeve of the developing device in order to remove toner from adhering to the conductive layer portion.
