Induction imaging system
Abstract
Abstract THE INVENTION RELATES TO AN INDUCTION IMAGING SYSTEM SUITABLE TO ACCOMPLISH DEVELOPMENT OF AN ELECTROSTATIC LATENT IMAGE AT A POINT REMOTE FROM THE PHOTOSENSITIVE SURFACE ON WHICH THE LATENT IMAGE IS ORIGINALLY FORMED. IN ONE EMBODIMENT, AN IMAGE SUPPORT MEMBER BEARING AN ELECTROSTATIC LATENT IS PRESENTED TO A SELF-SUPPORTING FILM IN THE FORM OF A CONTINUOUS INDUCTION WEBAN IMAGE BEING THEREBY INDUCED IN THE WEB, DEVELOPED THEREON AND SUBSEQUENTLY TRANSFERED TO A RECEIVER MATERIAL. THE CONTINUOUS INDUCTION WEB MAU BE CHARGED WITH A NEGATIVE, POSITIVE, GROUNG OR ALTERNATING POTENTIAL WHILE IN CONTACT WITH THE IMAGE SUPPORT MEMBER DEPENDING ON THE POLARLITY OF THE ELECTROSTATIC LATENT IMAGE ON THE IMAGE SUPPORT MEMBER; OR THE CONTINUOUS WEB MAY NOT BE EXTERNALLY CHARGED WHERE ONLY LINE COPY REPRODUCTION IS DESIRED. IN ANOTHER EMBODIMENT OF THE INVENTION, AN IMAGE SUPPORT MEMBER CARRYING AN ELECTROSTATIC LATENT IMAGE IS PRESENTED TO A RECEIVER MATERIAL HAVING A BULK RESISTIVITY IN THE RANGE OF FROM ABOUT 10**7 TO 10**14 OHM-CM. AN ELECTROSTATIC IMAGE IS INDUCED IN THE RECEIVER MATERIAL, DEVELOPED THEREON AND FIXED THERETO OR TRANSFERRED TO A SECONDARY COPY SHEET MATERIAL AND FIXED THEREON.
