Description of the Related Art Conventionally, paper, a plastic film provided with an image receiving layer, or synthetic paper has been used as an electrophotographic direct-writing type recording medium, and it is usually used in an electrophotographic copying machine (PPC) or a laser. A method of forming a toner image by a beam printer (LBP) and fixing the toner image is used. It is widely used for general records and record labels. When a lithographic printing plate is prepared using this recording method, the original plate after image formation is treated with an etchant to desensitize the non-image area and then applied to a lithographic printing machine to produce a large number of printed matter. Served to make. In such direct-writing recording by the electrophotographic method, so-called background stains in which toner adheres to the non-image area and toner around the image area.
There is a problem of so-called toner flying that adheres, and despite many improvements in the hardware, it is a problem that is difficult to solve, especially when a plastic film or synthetic paper is used as a recording medium. Also, when making a lithographic printing plate by this method, the one using paper often has problems in printing due to poor water resistance and poor dimensional stability, while plastic or synthetic paper is used for the support. In the case where there is such a problem, there is a problem that the background stains and toner jumps remarkably increase and the quality of the printed matter is affected.

わない。The image receiving layer in the present invention is a layer in which inorganic and / or organic particles are dispersed in a binder. The height of the unevenness on the surface of the image receiving layer from the center line is 2
The number of protrusions at the time of μm is 200 to 1000 / mm 2 , and the number of protrusions at the height from the center line is 6 μm is 4
Must be a 0 to 400 pieces / mm 2, preferably projection number is 350 to 850 pieces / mm 2 when the 2 [mu] m, and number of protrusions when the height of 6μm from the center line 7
More preferably, it is 0 to 250 pieces / mm 2 . If the number of protrusions is less than this range, the toner is likely to be crushed, and if the number of protrusions is greater than this range, the toner does not go into the gap between the protrusions and the toner is likely to be crushed, and the ground stain becomes conspicuous. The feature of the present invention resides in controlling the aspect of the surface irregularities as described above. Regarding the controlling method, for example, two kinds of inorganic and / or organic particles having different average particle diameters are mixed in an appropriate ratio. Examples of the method include, but are not limited to, a method of mixing and using the above method and a method of controlling the surface unevenness by controlling the drying rate. As the inorganic and organic particles used, ZnO, spherical synthetic silica, Ca
CO 3 , kaolin, talc, Al 2 O 3 , crosslinked polystyrene particles, crosslinked acrylic particles and the like can be mentioned. The average particle diameter is preferably in the range of 0.2 to 10 μm. Examples of the conductive layer in the present invention include, but are not limited to, those in which conductive particles are dispersed and applied in a binder, and those in which a conductive organic compound is applied. The conductive particles are preferably close to white, and examples thereof include whiskers of potassium titanate. The surface resistance value of the conductive layer is required to be 10 9 to 10 14 Ω / □. When the surface resistance value is 10 9 Ω / □ or less, the image density is low, and when it is 10 14 Ω / □ or more, toner skipping occurs. The polyester in the present invention is a polyester produced by polycondensing an aromatic dicarboxylic acid or its ester and glycol, and typical examples thereof include polyethylene terephthalate, polybutylene terephthalate, and polyethylene 2 −. 6-naphthalate and the like can be mentioned. The thermoplastic resin incompatible with the polyester in the present invention means a polyethylene resin, a polyolefin resin, a polystyrene resin, a polyacrylic resin, a polycarbonate resin.
Examples thereof include resin based resins, polysulfone based resins, and cellulose based resins. When the thermoplastic resin is made into a polymer mixture with the polyester, the thermoplastic resin is in the form of spherical or smooth spherical dispersion in the polyester, and when the polymer mixture is stretched, the polyester and the thermoplastic resin are dispersed. It is preferable that the particles easily peel off at the interface between the particles to form cavities, and polystyrene resins and polyolefin resins such as polypropylene are particularly preferable. The blending amount of the thermoplastic resin varies depending on the amount of target cavities. Also,
Inorganic particles such as titanium dioxide may be blended in order to impart hiding property. Further, if necessary, a composite film in which a surface layer and a center layer are laminated by a coextrusion method or the like may be used.

The method of laminating the conductive layer or the image receiving layer on the surface of the support is not particularly limited, but a coating method of applying a solution or dispersion on the surface of the support is particularly preferable. That is, it is preferable to apply a dry heat treatment after coating the support. Examples of coating methods include roll coating methods such as gravure and reversing, bar coating methods, doctor knife methods and air coating methods.
A usual method such as a knife or nozzle coating method can be used. Alternatively, a spraying method may be used. Furthermore, it is also possible to apply a mat coat, an antistatic agent or the like on the opposite surface for imparting transportability and antistatic property.
