An electrostatic recording body is constructed by laminating a glass
substrate transmissive of recording light, a first conductive layer
transmissive of recording light, a photoconductive layer exhibiting
conductivity by receiving recording light, an insulating dielectric
layer, and a second conductive layer transmissive of readout light, in
this order. DC voltage is applied to the electrostatic recording body by
a power source to charge both conductive layers, and an object is
irradiated with light from a recording light irradiating means, thereby
recording a electrostatic latent image at an interface between the
photoconductive layer and the dielectric layer. Then, the conductive
layers are short-circuited and charged at the same potential, thereby
redistributing electrical charges. Exposure is performed by scanning with
readout light from a readout exposure means, and current flowing out of
the electrostatic recording body is detected by a current detecting
means, thus reading out the electrostatic latent image.
