PROBLEM TO BE SOLVED: To eliminate the necessity of labor for forming a coloring agent layer and a developer layer separably on a copying sheet, make the fouling on a copy filling section hard to generate and combine together papers on which the developer layer and the coloring agent layer are formed preliminarily to manufacture a copy sheet of single sheet shape. SOLUTION: The end edge of an upper paper 2 with a coloring agent layer 4 on one face and the end edge of the lower paper 3 with a developer layer 5 on one face are press bonded together, and the thickness of an overlapped section is reduced and the papers are continued each other. The developer layer 5 on the lower paper 3 is formed on the side of a face facing the coloring agent layer 4 when the lower paper 3 is folded on the side of the coloring agent layer 4 on the upper paper 2.
