Abstract
The present invention provides an electrostatic information-recording medium including an electrode layer (13) and a charge-retaining layer, in which said charge-retaining layer is formed of a laminate of a resin layer (11a) having a low glass transition temperature with a heat-resistant, insulating layer (11b), or an electrostatic information-recording medium comprising at least an electrode layer (13) and a charge-retaining layer (11) in which said charge-retaining layer (11) is formed of a polymer layer (12) containing pentafluorostyrene as a monomer component and having a weight-average molecular weight of 10,000 to 2,000,000, or which includes a photoconductive layer (44) and a charge-retaining layer (43) between a pair of electrodes (42) and (45) and is designed to carry out exposure with the application of voltage between both said electrodes (42) and (45) or apply voltage between both said electrodes (42) and (45) while exposure is carried out, thereby forming an electrostatic latent image, which is then carried on said charge-retaining layer (43) by releasing said charge-retaining layer ( 43) from said electrode 42, or which includes a charge transport layer (51) on an ele…
