Abstract

PURPOSE: To achieve the stabilization of potential controlling by grounding the grid of an AC or DC corona discharging means by way of a resistance.
CONSTITUTION: The grid 22 of an Ac or DC corona discharger 3 is grounded by way of a resistance 24. As a result of this, light image exposure is done by an exposure light source 19 through the AC or DC corona discharger 3 on the photoreceptor 1 charged by a primary charger 2, after which the electrostatic latent images formed through full surface exposure by a lamp 4 are developed under the action of a developing electrode 5 and are further transferred onto transfer paper 8 and are fixed by a fixing device 9, at which time the current ratio of the AC or DC corona discharger 3 is made constant to obviate the decrease in discharging and charging efficiency, hence the potential controlling for converging the bright part potentials or dark part potentials on the photoreceptor 1 to the target values is stabilized.
