Abstract of the Disclosure A method is disclosed for performing electric discharge recording on the recording surface of an electric discharge recording material using a discharge recording stylus. An electrically anisotropic non-recording layer is interposed between the recording surface and the discharge recording stylus. This non-recording layer is prepared by dispersing a metal powder in a resin matrix and has a surface resistance of at least 108 ohms and a volume resistance of not more than 104 ohms-cm. Electric discharge recording is performed through the non-recording layer. Also disclosed is 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 more than 102 ohms-cm.
