a new method for structural electrophotographiques images including images

摘要

Fixing is by electrophoretic deposition of resin particles from a solvent, then eliminating the excess solvent. The solvent vehicle in which the resin is dispersed has a resistivity 109 ohm/cm and a dielectric constant 3. The solid content of the dispersion is between 0.125-5 g/litre and pref. resins are alkyd, PF, methacrylate, vinyl or mixtures of these. The dispersion contains a charge controlling agent. The electrode is placed 0.25-2 mm from the image bearing product with a polarisation potential of 800-2000V. Particularly used for a electrophotographic product containing an organic photoconductor in which the image is developed using a liquid developer contg. coloured particles. The liquid used for the developer and the resin dispersion are either the same or compatible.
