PURPOSE: To copy even a printing result obtained by an electrophotographic printer on the second and lower paper by providing multiple paper having a sublimable dyestuff on the surfaces of the second and after sheets of paper.
CONSTITUTION: Multiple paper 5 is provided with a sublimable dyestuff 2 on the surfaces of the second and after sheets of plane paper 4. Namely, when the multiple paper 5 is fixed under heat and pressure with a toner 3 transferred on the surface of plane paper 1 by a transfer part of an electrophotographic printer, the plane paper 1 has such a temperature distribution as a part corresponding to the toner 3 is lower in temperature than the other part by selecting the material of the toner 3. Therefore, the sublimable dyestuff 2 is sublimated to the surface of the plane paper 1 at the temperature of a part of the plane paper 1 uncorresponding to the toner 3 but fused to the surface of the plane paper 4 at the temperature of the other part corresponding to the toner 3. Thus, the same printing result as the surface of the plane paper 1 can be obtained on the surface of the plane paper 4. Two or more sheets of paper can be overlapped by selecting the temperature characteristics of the sublimable dyestuff.
