ABSTRACT:
An electrostatic print head system is disclosed which comprises an ion modulated electrostatic print head, a means for supplying unheated dehumidified air having a relative humidity of less than about 20 percent at or near ambient temperature, and a means for directing the dehumidified air at, near or through the print head. The print head may comprise a modulated aperture board having a plurality of selectively controlled apertures therein and an ion generator for providing ions for electrostatic projection through the apertures. The electrostatic print head system may be used for forming latent electrostatic images and employed in an electrostatic printer which further comprises a means for developing the latent electrostatic images.
