Abstract
Abstract A recording material including at least a liquid dispersion medium and an electrolyte contained therein; the electrolyte providing substantially no halogen ion in the liquid dispersion medium under electrolytic dissociation; the recording material being capable of changing its adhesiveness when imparted with a voltage by means of a pair of electrodes, thereby to selectively adhere to either one of the pair of electrodes.
