Abstract: A METHOD IS PROVIDED FOR THE DEVELOPMENT OF ELECTROSTATIC LATENT IMAGES FORMED ON A SUPPORT MEMBER. MAGNETIC TONER PARTICLES ARE MAGNETICALLY DRAWN OVER A NONMAGNETIC SURFACE, WHILE ON SAID SURFACE A CHARGE IS APPLIED TO THE TONER PARTICLES WHICH IS OPPOSITE IN POLARITY TO THAT OF THE ELECTROSTATIC LATENT IMAGE. A STREAM OF GASEOUS MATERIAL IS DIRECTED AGAINST THE CHARGE TONER PARTICLES CARRIED ON THE NON-MAGNETIC SURFACE TO FORM A SUSPENSION OF SAID PARTICLES IN SAID GASEOUS MATERIAL. THIS SUSPENSION, OR POWDER CLOUD, IS CONTACTED WITH SAID ELECTROSTATIC LATENT IMAGE TO THEREBY DEVELOP SAID IMAGE WITH SAID TONER PARTICLES.
