PROBLEM TO BE SOLVED: To provide electrophotographic transfer paper, capable of satisfactorily coping with the demands for higher image quality and higher speed for recent photographic copying machines, printers, and so on in terms of curling, running, and appearance quality, even if the electrophotographic transfer paper contains newspaper used paper and/or magazine used paper, combined in large proportion. SOLUTION: The electrophotographic paper contains 50 to 100 mass% of used paper pulp, having at least newspaper used paper or magazine used paper as the main constituent. In the electrophotographic paper, ISO whiteness index is 75 to 95%, the degree of moisture shrinkage is 0.6% or less, and a critical length in a cross direction (CD direction) measured by a Clark rigidity test method is 15 cm or longer.
