Electrostatic recording medium having reading-side photoconductive layer of inorganic oxide
An electrostatic recording medium includes: a first conductive layer which is transparent to radiation for recording; a recording-side photoconductive layer which is formed above the first conductive layer and becomes conductive when the recording-side photoconductive layer is exposed to the radiation for recording; a charge-accumulation region which is formed above the recording-side photoconductive layer and accumulates electric charges being generated in the recording-side photoconductive layer and having a latent polarity; a reading-side photoconductive layer which is formed of inorganic oxide above the charge-accumulation region and becomes conductive when the reading-side photoconductive layer is exposed to an electromagnetic wave for reading; and a second conductive layer which is formed above the reading-side photoconductive layer and transparent to the electromagnetic wave for reading.
1 . An electrostatic recording medium for recording an electrostatic latent image, comprising:
a first conductive layer which is transparent to radiation for recording;
a recording-side photoconductive layer which is formed above said first conductive layer and becomes conductive when the recording-side photoconductive layer is exposed to said radiation for recording;
