Title: Multiple sheets copying method
Inventor: SATOU TSUTOMU
IPC: G03G13/00
Filed: 1979-08-23
Abstract: PURPOSE:To enable copies of superior image quality to be obtained in multiple sheets from the same electrostatic latent image by forming a recoverable electrostatic latent image by the use of a composite photoreceptor and recovering electrostatic latent image potential according to need. CONSTITUTION:A photoreceptor 1A consists of a photoconductive layer 11 which is made conductive by the light A of the specific wavelength and a photoconductive layer 12 which is made conductive by the light B of another wavelength. This is subjected to predetermined primary charging in a dark place, whereby the photoconductive layer 12 is charged. Thence, it is subjected to the secondary charging of the polarity opposite from that of the primary charging to charge the photoconductive layers 12, 11 so as to become mutually opposite in direction. The photoreceptor 1A of this state is subjected to exposure to form an electrostatic latent image followed by developing and transferring, during which the electrostatic latent image gradually attenuates. If the photoreceptor 1A is irradiated uniformly by the light B upon lowering of its latent image potential, the latent image potential is recovered if there is sufficient positive charge on the back surface of the photoconductive layer 12. Multiple sheets of copies may be obtained by repeating developing and transferring by using this.

IPC: H04N5/64
Filed: 1994-04-21
Abstract: PURPOSE:To dispense with a means for detecting the timing for starting the drive in the standing direction of a display panel.
