Abstract

In an electrostatic recorder including: a first electrode for transmitting radioactive rays; a recording photoconductive layer irradiated with the radioactive rays to generate charge; a charge transportation layer; a storage unit for storing the charge as an electrostatic latent image; a reading photoconductive layer irradiated with a reading light to generate charge; and a second electrode, the first electrode, the recording photoconductive layer, the charge transportation layer, the storage unit, the reading photoconductive layer, and the second electrode are laminated in this sequential order. The electrostatic recorder further includes a suppression layer provided between the reading photoconductive layer and the second electrode to prevent interfacial crystallization generated in the reading photoconductive layer. In the electrostatic recorder, the interfacial crystallization of the reading photoconductive layer is prevented without reducing reading efficiency. As the material of the suppression layer, polyvinyl alcohol which is an organic polymer having an OH group is used.
