Abstract

The authors have developed a highly effective image eraser for decolorable toner that comprises leuco dye and developer. Using a heat eraser requiring minimal, printed paper with decolorable toner can be reused repeatedly. However, the erasing is visible in spite of discoloring because of the binding resin remaining on the paper. The new image eraser employs an erasing process consisting of rubbing, dust cleaning, and heating. The processes cause the original image to completely disappear. This method achieved both complete destruction of the printed information and renewal of the used paper. A paper can be reused at least five times in the case that the erasing condition is such that the original image completely disappears. This paper describes the mechanism of the erasing processes.
