    摘要: An electrostatic recording media comprising a support having first and second surfaces, a conductive clay layer on the first surface of the support, at least one dielectric layer present on the conductive layer, and a non-clay conductivizing agent incorporated into the support from the second surface is described. The element is used in electrostatic imaging systems to produce images having improved density in relatively low humidities.
