DEFINITION

Classification: 347/112

Electrostatic:

(under subclass 111) Subject matter wherein an electrostatic charge is deposited onto, or discharged from, the medium to directly or indirectly form a visible image thereon in accordance with an electrical information signal representing the image.

(1) Note. The medium includes an intermediate substrate (belt or drum) for receiving a latent or a visible image; or a permanent substrate for receiving a transferred visible image.

SEE OR SEARCH THIS CLASS, SUBCLASS:

159, for an electric recorder wherein an image is formed by an electrical discharge from a head onto the medium.
