Abstract: <P>PROBLEM TO BE SOLVED: To provide a reproducible recording medium, and to provide a reusable transfer material having strong adhesion with toner when an image is formed once by easily separating the toner and repeatedly using it without using a chemical such as a solvent in the reproducing method.  <P>SOLUTION: In the transfer material in which the toner can be erased and an image forming method in which thermal expansion coefficients of a main binder of the toner necessary for the image formation and a resin of a surface forming a porous surface are different, minute holes exist on the surface of the transfer material. When the image is formed, the toner is formed in the holes, and the toner is fallen into the holes by expansion of the toner due to heating. Furthermore, when the reusable transfer material is reused, size of the holes is widened by giving heat, and the toner forming the image therefrom is scratched.  <P>COPYRIGHT: (C)2004,JPO
