PROBLEM TO BE SOLVED: To provide an electrophotographic transfer paper capable of suppressing the occurrence of heat curling even when being heated by a copying machine or the like. SOLUTION: When the electrophotographic transfer paper is halved into a surface layer and a back layer, a starch content in one side layer becomes more than that in the other side layer, and one side surface is a layer having a small shrinkage ratio when being heated in a raw paper prior to coating. Therein, the starch content is adjusted so as to be higher in the layer having a small shrinkage ratio when being heated in a raw paper and, therefore, a moisture amount which is evaporated from starch included in the layer having a small shrinkage ratio when being heated by a machine of transferring electrophotography becomes more than that from the starch included in the other side layer. As the result, a difference of shrinkage ratio between the layer having a small shrinkage ratio and the other side layer can be reduced as compared to when being heated in the state of raw paper and, therefore, the occurrence of heat curling can be suppressed.
