Abstract
An electrophotographic printing machine in which a latent image is recorded on a photoconductive surface. The latent image is developed with charged, insulating marking particles and magnetic, polar or polarizable marking particles. The charged, insulating marking particles optimize development of low density lines in the latent image with the magnetic, polar or polarizable marking particles optimizing development of halftones in the latent image.
