Claims
- 1. An electrostatic information-recording medium comprising at least an electrode layer and a charge-retaining layer, characterized in that said charge-retaining layer is a
- pentafluorostyrene polymer layer and having a weight-average molecular weight of 10,000 to 2,000,000.
- 2. An electrostatic information-recording medium comprising at least an electrode layer and a charge-retaining layer, characterized in that said charge-retaining layer is obtained by the successive lamination of a fluoropolymer layer and a pentafluorostyrene polymer layer and having a weight-average molecular weight of 10,000 to 2,000,000 on said electrode layer.
- 3. A process for recording and reproducing electrostatic information, characterized by:
- locating a photosensitive member including a photoconductive layer on at least an electrode layer in opposite and contact or non-contact relation to an electrostatic information-recording medium obtained by laminating on at least an electrode layer a
- pentafluorostyrene polymer layer having a weight-average molecular weight of 10,000 to 2,000,000, and
- forming an electrostatic charge pattern on said recording medium by exposing said recording medium to light with the application of voltage between both said electrodes or applying voltage between both said electrodes while said recording medium is exposed to light.
- 4. A process for recording and reproducing electrostatic information, characterized by:
- locating a photosensitive member including a photoconductive layer on at least an electrode layer in opposite and contact or non-contact relation to an electrostatic information-recording medium obtained by the successive lamination on at least an electrode layer of fluoropolymer layer and a pentafluorostyrene polymer layer and having a weight-average molecular weight of 10,000 to 2,000,000, and
- forming an electrostatic charge pattern on said recording medium by exposing said recording medium to light with the application of voltage between both said electrodes or applying voltage between both said electrodes while said recording medium is exposed to light.
