Abstract
A charging device () includes electrospray means for inducing electrospraying through application of a voltage to an incoming liquid (), in order to produce charged liquid droplets (). The device () charges a photoreceptor drum () by means of the liquid droplets (). Hence, the invention provides a charging device capable of reducing ozone production while preventing the charging device and the electrostatic latent image carrier from degrading or wearing out from friction between the device and the carrier and provides also an image forming device incorporating the charging device.
