Abstract
This invention provides a method for using paper repeatedly by flaking and removing an image from the paper, even if the image has been touched up on the paper with handwriting, and a preferable printing tool used in the method. The method includes the steps of touching up the image on the paper with the printing tool containing a main component of a colored thermoplastic resin particle and being formed into a stick shape by solidifying the resin particle alone or with binder resin sticking to the resin particle. The image can be formed on the paper with a liquid-applying type of printing tool having a liquid container containing a resin dispersion liquid being formed by dispersing the resin particle in a solvent. Regenerating of the paper by removing the touched-up image from the paper comprises the steps of wetting the paper through a treatment liquid such as water, and while heating the resin particle of the image, adhering the resin particle to a flaking member having a greater adherent force to the resin particle than the adherent force between the resin particle and a surface of the paper so as to flake and remove the resin particle from the surface of the paper.
