PURPOSE:To improve printing resistance, and to make a picture distinct by laminating a polyolefin group resin film layer containing conductive inorganic fine particles and a liquefied substance and an ionomer resin film layer containing conductive inorganic fine particles and a liquefied substance. CONSTITUTION:Fixed quantities of conductive inorganic fine particles and liquefied substances are each added to a polyolefin group resin and an ionomer resin, and mixed sufficiently by a kneader such as a Banbury mixer. A mixture is two- layer simultaneous co-extruded or three-layer extruded by a proper extruder, or films are formed severally, pasted together and laminated, and a laminate is changed into a film, thus manufacturing an electric recording copying base. Carbon black, graphite, etc. are used as conductive inorganic fine particles, and compounded in 10-50wt%. Liquidized paraffin, mineral oil, etc. are used as the liquefied substance, and compounded in 5-20wt%. |
