Title:
PHOTOSENSITIVE MEMBER AND ELECTROSTATIC DATA RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/1990/011551
Kind Code:
A1
Abstract:
A photosensitive member having an electrode on the front surface thereof and a photoconductive layer stacked on the electrode. The member faces an electrostatic data recording medium which comprises a charge-holding layer having an electrode on the back surface. The photosensitive member may be in contact with the recording medium. When a voltage is applied across the electrodes, an exposure is carried out to form an electrostatic charge pattern in the electrostatic data recording medium, the electrostatic charge pattern being in correspondence with the exposure pattern. The layer structure of the photosensitive member and the photoconductive layer and the method of forming the photoconductive layer are improved, enabling the recording of electrostatic data on the electrostatic data recording medium with high sensitivity. Further, the contrast in charges of data between the exposed portion and the unexposed portion can be improved.
