PROBLEM TO BE SOLVED: To provide a copying sheet, by which copying with a no-pressure applicable non-impact type printer is possible. SOLUTION: In the copying sheet 1, an upper sheet 2 and a lower sheet 3 are piled up and bound under the condition that heat sensitive recording agent layers 9 and 10, which develop and change color through heat, are formed on the portion, in which a copying entry is made, of the piled-up surface of the lower sheet 3 and, on the other hand, heat sensitive recording agent layers 7 and 8, which develop or change color through heat, are formed on the portion oppositely contacting with the heat sensitive recording agent layers 9 and 10 of the lower sheet 3 in the upper sheet 2 so as to be copied to the heat sensitive recording layers 9 and 10 through the heating in the fixing process of toner in the non-impact type printer. |
