Abstract
Disclosed is an electrostatic recording method for forming an electrostatic latent image on a dielectric electrostatic recording layer provided on a conductive support. The relationship between the thickness d[.mu.m] and the specific dielectric constant .epsilon..sub.s of the electrostatic recording layer is such that the ratio of d[.mu.m] to .epsilon..sub.s, i.e. d/.epsilon..sub.s [.mu.m], is not larger than 1.65[.mu.m] when the image recorded is of reflection type and not larger than 1.5[.mu.m] when it is of transmission type. The latent image formed on the recording layer is developed by use of electrophotographic liquid developer. Also disclosed is an ionizing radiation image recording method wherein ionizing radiation carrying image information is directed onto a material which generates photoelectrons or a gas which is dissociated upon receipt of the ionizing radiation to an extent corresponding to the intensity of the radiation. In this method, the ratio of the thickness of the electrostatic recording layer to the specific dielectric constant is selected to be not larger than 1.5[.mu.m] when the image is of reflection type and not larger than 1.0[.mu.m] when it is of transmission type.
