-41- ABSTRACT OF THE DISCLOSURE A liquid crystal, particularly a ferroelectric liquid crystal, is interposed between an electroconductive member and an electric charge accepting member to form a liquid crystal device. In the first step of image formation, a uniform polarity of charge is imparted to the entirety or a part of the electric charge accepting member whereby the liquid crystal is uniformly oriented to its first stable state under a uniform electric field thus formed therethrough. In the second step, the reverse polarity of charges are given imagewise to the charge accepting member, whereby the liquid crystal is re- oriented imagewise to the second stable state to form an image.
