ABSTRACT:
An offset electrostatic printer is disclosed which comprises (a) an ion modulated electrostatic print head for forming latent electrostatic images, (b) a dielectric imaging member comprising a layer of dielectric material, (c) means for developing a latent electrostatic image on the dielectric imaging member, (d) means for transferring a developed electrostatic image from the dielectic imaging member to an image receiving surface, (e) means for supplying unheated dehumidified air having a relative humidity of less than about 20 percent at or near ambient temperature, and (f) means for directing the dehumidified air at, near or through the print head and at or near the dielectric imaging member.
