Abstract

An image formation apparatus using a recording medium including a scattering-mode light-modulation member which takes an opaque state in response to a heat and takes a transparent state in response to an electric field. The apparatus comprises an electrode device disposed in opposed relation to the recording medium and a charge removal device facing or in contact with the recording medium. The electrode device applies an electric field to the recording medium thereby completely erasing an image previously recorded in the recording medium and the charge removal device removes charge left in the recording medium due to application of the electric field by the electrode device. After the erasure, the recording medium is heated by a thermal head in accordance with an information signal from an external device so as to form a new image in the recording medium.
