Abstract: The invention provides a method for easily and promptly erasing an image (including a character) formed on a printed article with a low cost, and an apparatus employing such method. A printed article bearing an image formed on a surface including an inorganic pigment is exposed to a reactive gas generated by creeping discharge or corona discharge induced by a voltage applied between a pair of opposed electrodes, whereby the image is erased.

Abstract: Disclosed is a method for erasing an image which is formed on a recording medium by applying an ink containing a dye. This image erasing method is characterized in that the image is exposed to an oxidizing gas which is generated by dielectric barrier discharge. Also disclosed are an apparatus for carrying out such an image erasing method, and a method for reclaiming a recording medium wherein such an image erasing method is performed.
