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.

Electrostatic recording material

In an electrostatic recording material being composed of a multi-layered sheet support having an electroconductive layer and a dielectric layer formed successively thereon, the number of projections having a height of 10 .mu.m or more from the flat surface is limited to a maximum of 50 per 0.1 m.sup.2, so that the material has excellent properties and can produce prints of very high quality.

An electrophotographic image transfer paper for a copier including a fixing operation, comprises a sheet of raw paper, and a receiving layer on the paper for reducing blistering of the sheet during fixing of an image on the sheet, the receiving layer including a coating on at least one side of the sheet, having a center-line-average surface roughness not more than 2.0 micrometer and an air permeability less than or equal to 4,000 seconds.
