Abstract
A voltage is selectively applied between two electrodes (emitter and gate) disposed at a short distance to create an intense electric field between the electrodes. Electrons emitted by the field emission are accelerated by the intense electric field and collide against a fluorescent layer so that light can be emitted from portions of the fluorescent layer. With a recording head of the above construction, an electrostatic latent image is formed on a photosensitive drum.
