Claims
- 1. A cathode ray tube pickup device comprising:
- a photosensitive medium having a dielectric layer, a photoconductive layer and a conductive layer;
- means for uniformly charging the surface of said photosensitive medium;
- means for uniformly discharging the charged surface of said photosensitive medium;
- an optical fiber tube disposed closely adjacent to the surface of said photosensitive medium to apply a light image to the previously charged and discharged surface thereof to form a latent image upon said surface; and
- means for developing the latent image on the surface of said photosensitive medium with a liquid developer including a toner having a charge polarity for developing that portion of the latent image corresponding to the light portion of the light image, wherein the developed image is a negative of the light image.
- 2. A cathode ray tube pickup device as set forth in claim 1, further comprising means for removing excess liquid developer from the surface of said photosensitive medium, and means for transferring the developed image onto a transfer medium.
