Abstract
A polarization reversion pattern is formed in ferroelectrics in accordance with image information. An image is obtained by surface charges corresponding to the polarization reversion pattern. The ferroelectrics are composed of an inorganic ferroelectric oxide such as LiNbxTa1-xO3(0≦x≦1).
Claims60
An image forming method comprising the steps of:
- subjecting ferroelectrics to a distribution of heat corresponding to image information simultaneously with application of an electric field, in order to form a polarization reversion pattern in said ferroelectrics in accordance with said image information;
- applying a change in temperature to said ferroelectrics so that surface charges corresponding to said polarization reversion pattern are generated by a pyroelectric effect;
- and
- obtaining an electrostatic latent image by said surface charges;
- wherein an inorganic ferroelectric oxide is employed as said ferroelectrics.
