Abstract

L'INVENTION CONCERNE UNE METHODE DE DEVELOPPEMENT D'UNE IMAGE LATENTE ELECTROSTATIQUE FORMEE A LA SURFACE D'UN ORGANE ELECTROPHOTOGRAPHIQUE EN UTILISANT UN PRODUIT LIQUIDE DE VIRAGE FORME DE PARTICULES DE VIRAGE EN SUSPENSION DANS UN LIQUIDE ISOLANT ET UNE ELECTRODE DE DEVELOPPEMENT. SELON L'INVENTION, UNE TENSION ALTERNATIVE DE POLARISATION EST APPLIQUEE ENTRE L'ELECTRODE DE DEVELOPPEMENT 21 ET L'ORGANE ELECTROPHOTOGRAPHIQUE 11 A TRAVERS LE PRODUIT LIQUIDE DE VIRAGE 23 PENDANT L'OPERATION DE DEVELOPPEMENT. L'INVENTION S'APPLIQUE NOTAMMENT A L'ELECTROPHOTOGRAPHIE.THE INVENTION CONCERNS A METHOD FOR DEVELOPING AN ELECTROSTATIC LATENT IMAGE FORMED ON THE SURFACE OF AN ELECTROPHOTOGRAPHIC ORGAN BY USING A LIQUID TURNING PRODUCT IN THE FORM OF TURNING PARTICLES IN SUSPENSION IN AN INSULATING LIQUID AND A DEVELOPING ELECTRODE. ACCORDING TO THE INVENTION, AN ALTERNATIVE POLARIZATION VOLTAGE IS APPLIED BETWEEN THE DEVELOPMENT ELECTRODE 21 AND THE ELECTROPHOTOGRAPHIC BODY 11 THROUGH THE LIQUID TURNING PRODUCT 23 DURING THE DEVELOPMENT OPERATION. THE INVENTION APPLIES IN PARTICULAR TO ELECTROPHOTOGRAPHY.
