Abstract
The invention provides a method for easily and promptly erasing an image (including a character) formed on a printed article, 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 application between a pair of opposed electrodes, whereby the image is erased.
