  • Method of developing electrostatic images using wide latitude toner
    Patent number: 4055419
    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.
    Type: Grant
    Filed: August 23, 1976
    Date of Patent: October 25, 1977
