ABSTRACT:
A method for cleaning waste paper by removing toner-images formed thereon. An emulsion formed cleaning solution, which has a water component, an organic solvent dissolving a resin component, and a surface active agent to form a solution into the emulsion, is applied to the waste paper. The waste paper has a toner-image which is formed by toner-particles which have a resin component. The distance between the fibers of the paper is widened by the water component of the cleaning solution. The resin component of the toner is dissolved by the organic solvent of the cleaning solution.
