Abstract: Toner is placed on to the image-forming surface and then is transferred onto the image-carrying medium based upon adhesion force. A sharp image is formed without suffering from the dispersion of toner during the transfer process. In addition, the adhesion force-based image forming device is simpler in construction and advantageously produces substantially no ozone. One preferred embodiment transfers heat sensitive toner to an image-carrying medium by increasing the adhesion force of the toner and almost simultaneously decreasing the adhesion force of the image-forming surface with the raised temperature.

Charges may be generated applying either the piezoelectric or the pyroelectric effect exhibited by ferroelectric films.

Abstract: An image forming apparatus forms an electrostatic latent image on a latent image forming body having a dielectric material layer on its surface when a write electrode comes into contact with the dielectric material layer. The image forming apparatus develops the electrostatic latent image with a charged developer, and transfers a visual image thus obtained onto recording paper. The dielectric material layer is composed of a PZT (lead titanate zirconate) which is formed through crystal growth by the hydrothermal method. The dielectric material layer has a high relative dielectric constant and exhibits the pyroelectric effect. Furthermore, since the dielectric material layer is composed of the PZT which is formed through crystal growth by the hydrothermal method, the dielectric material layer can be formed without a heat treatment at a high temperature.

Abstract: Pyroelectric materials are used to create net charge/surface potentials for use in xerographic charge and transfer steps. Heating and cooling a pyroelectric film, such as, polyvinylidene fluoride induces thermal expansion or contraction which create surface charge density changes that can be used to charge a photoconductive surface and/or transfer an image from a photoconductive surface to a copy sheet.

Abstract: A novel process is disclosed for the manufacture of protected, distortion-free, full-color electrographic images for use on large format posters, billboards and the like. A novel electrographic element is also disclosed, which includes a base, a release layer and a combined transparent dielectric and adhesive layer which is substantially tack-free, at ambient pressure and temperature. The novel electrographic imaging process includes the steps of: A) producing a toned image layer on the surface of the electrographic element and B) pressure laminating the receptor substrate, optionally at an elevated temperature to the toned image layer to form the completed electrographic image. The base and release layer may be stripped from the dielectric/adhesive layer which then serves to protect the transferred, toned, electrographically generated image from abrasion and environmental contaminants.
