ABSTRACT:
A method is disclosed for visibly reproducing light or poor images upon an exposed electroconductive surface. A liquid developer is provided, and used in the method, comprising a negative toner material having no cut-off which is deposited on slightly discharged and uncharged areas resulting from exposure to minimum degrees of illumination. The toner material includes electrostatically charged particles in combination with a chemically active liquid solution which solution increases the ability of the particles to adhere to slightly discharged as well as an uncharged surface on the exposed photoconductive paper.
