The electrophotographic transfer paper in the present invention has superior high-speed throughput performance despite low basis weight and a low coating weight, therefore, good for high-speed copy machine and printer properties, especially, when it contained a printability improver in the coating layer, it has a good ink adhesion property and surface strength required in offset printing.
