Abstract

1452520 Developing electrostatic latent images DENNISON Mfg CO Ltd 16 Oct 1973 [16 Oct 1972] 48246/73 Heading G2H Electrostatic latent images on the upper side of sheet S are developed by liquid developer sprayed from nozzle 24 and contained in tank 17, as the sheet travels between metal mesh electrodes 19, 31 with its lower surface in contact with the upper surface of electrode 31. Preferably the electrodes have a coating, no greater than 1 mil, of dielectric material such as epoxy resin, and are earthed.
