Abstract
1,251,442. Electro-photographic development. FUJI SHASHIN FILM K. K. Feb. 20, 1969 [Feb. 20, 1968], No.9315/69. Heading G2H. Electrostatic latent images on insulating and photo-conductive surfaces are developed with a liquid developer comprising a toner having a maximum particle diameter below 1Á in an insulating, non-polar carrier liquid containing a dissolved resin, and then before the surface dries, washing with a volatile liquid in which the resin is less soluble than in the carrier liquid so that the resin is deposited on the image-bearing surface. The washing liquid may contain toner in a concentration up to 10% of that in the developer but contains no other non-volatile ingredient. Preferably the resin is a long-oil alkyd, epoxy ester, xylene- HCHO terpene, styrene-modified alkyd, or copoly (butyl methacrylate/styrene) resin or a rosin-modified phenol-HCHO resin cooked in boiled linseed oil. The washing liquid may be an iso-paraffinic hydrocarbon or a chlorofluorinated hydrocarbon. Specified carrier liquids comprises kerosene, cyclohexane, decalin, isooctane, tetralin, vegetable oil and/or toluol. The development/washing process enables washing to be effected using high speed currents and excess washing liquid to be removed by squeeze rollers and is particularly useful for forming multi-colour images by repeated charging, exposure and development of a photo-conductive surface.
