  • Image development method
    Patent number: 4334002
    Abstract: An electric field is established in the gap between an imaging surface and an opposing electrode surface inducing movement of particles from suspension within a developer in the gap toward the opposing electrode surface. A voltage pattern generated on the imaging surface causes deposit of the developer particles in image relation on the opposing electrode surface or on a printing surface positioned adjacent thereto, by a repulsive action between the imaging surface and the particles having an electrostatic charge of the same polarity.
