A method for performing electric discharge recording on the recording surface of an electric discharge recording material using a discharge recording stylus, which comprises interposing an electrically anisotropic non-recording layer between the recording surface and the discharge recording stylus, said non-recording layer being prepared by dispersing a metal powder in a resin matrix and having a surface resistance of at least 108 ohms and a volume resistance of not more than 104 ohms-cm, and performing electric discharge recording through the non-recording layer; and a composite discharge recording material which comprises (a) an electric discharge-breakable semiconductive resin layer having a surface resistance of 105 to 1016 ohms and a volume resistance of 103 to 1014 ohms-cm, (b) a metal-containing resin layer having a surface resistance of at least 108 ohms and a volume resistance of not more than 104 ohms-cm, which is laminated on one surface of the semiconductive resin layer (a) and is prepared by dispersing a metal powder in a resin matrix and (c) a conductive layer laminated on the other surface of the semiconductive resin layer (a) and having a surface resistance of not more than 104 ohms and a volume resistance of not than 102 ohms-cm. |
