Title: Electrostatic copying device
Inventor: MATSUO MAKOTO
IPC: G03G15/00
Filed: 1988-05-20
Abstract: PURPOSE:To maintain electric charger for many hours and to accomplish toner development any time by imposing a voltage between a photosensitive body and a charge holding medium, exposing a sensitive material to form an electrostatic latent image on the charge holding medium, and toner developing said image. CONSTITUTION:The charge holding medium 3 is set to the photosensitive body 1 with a space of about 10mum, and a voltage is imposed between electrodes 7 and 13 with a power supply 17. When light is made incident from the photosensitive body 1, the photoconductive layer 9 of the part where light is made incident shows electrical conductivity, a discharge is generated between an insulating layer 11 and said layer 9 to accumulate electric charges in the insulating layer 11. Though the surface charge on the insulating layer 11 is exposed to air environment, it is maintained for many hours regardless of a light or dark place because air has a good insulating character. Therefore, a toner development is not needed immediately after the electrostatic latent image is formed, and the charger holding medium where the electrostatic latent image is formed is maintained. Afterward said image can be developed and transferred at any place and any time.
