ABSTRACT:
An electrostatic recording material, capable of recording clear resist marks and colored images without generating a lead edge fog and colored image slippage, comprises an insulating support 1, an electroconductive intermediate layer 2 formed on a surface of the support, a dielectric layer 3 formed on the electroconductive intermediate layer, and a pair of electroconductive side edge layers 4, 5 formed on a record-starting side edge portion of the dielectric layer, in which side a recording operation in a transversal direction of the recording material is started, and on a record-ending side edge portion of the dielectric layer, in which side the recording operation is ended, extending along the longitudinal axis of the recording material, spaced from each other, and each having a surface resistivity of from 1.times.10.sup.4 to 5.times.10.sup.5 .OMEGA.; the electroconductive record-starting side edge layer having a surface resistivity ratio of 2:1 to 10:1 to the electroconductive record-ending side edge layer.
