Abstract: 1,259,880. Electro-photographic development. XEROX CORP. Feb. 21, 1969 Feb. 23, 1968], No. 9486/69. Heading G2H. Electrostatic images are developed by contact with a suspension of developer particles in a carrier liquid, said suspension having immersed therein at least one coronode to which is applied a potential sufficient to deform the liquid surface. The coronode(s) may be in the form of a needle, a knife edge or a wire, and positioned in the liquid so as to, on energization either (1) deform the surface of the liquid sufficiently for it to contact the image bearing surface, or (2) electrostatically atomize the suspension. The electrostatic images may be formed on a dielectric drum or by charging and exposing a photo-conductive drum, and the developed image transferred to a receptor sheet.

Abstract: A piezographic imaging process includes the use of a composite photoreceptor structure that includes a piezoactive layer that enables Xerographic imaging without corona charge/transfer subsystems. Flexure of the photoreceptor structure creates electric fields sufficient for the creation of developable latent electrostatic image patterns. Flexure of the photoreceptor structure following development generates an electric field for transfer of toner images onto paper.

Abstract: A cylindrical and rotatable resonating assembly, generally for use in electrostatographic applications. The resonating assembly is preferably positioned along a longitudinal axis generally transverse to the process direction of movement of a toner bearing member, for applying uniform vibratory energy thereto. The cylindrical form of the resonating assembly allows for rotation of the assembly while remaining in contact with the image bearing member to reduce frictional forces between a contact surface of the resonating assembly and the image bearing member which, in turn, reduces wear of the resonating assembly as well as the image bearing member. The resonating assembly may include a plurality of discrete individual resonator elements, each including a vibratory energy producing segment, such as a piezoelectric transducer, for generating vibratory energy and a waveguide segment coupled to the vibratory energy producing segment for transporting the vibratory energy from the transducer to the image bearing member.

Abstract: Pyro-electric charging device (60) for charging grounded photo-conductive surface member (90) has a cylindrical conductive roll support structure (62) completely covered by a layer of pyro-electric film (61). The roll is placed in contact with the photo-conductive surface (97) and a heater (64) communicating with the film is used to produce surface potentials that charge the surface. Also claimed is printing apparatus having a photo-conductive surface, the claimed pyro-electric charging device, an imaging device for discharging the photo-conductive surface in image-wise configuration, a device for developing the image on the photo-conductive surface, a transfer device for transferring the image from the photo-conductive surface to a copy sheet, a fuser for fusing the image to the copy sheet, and an output device for receiving the copy sheet from the fuser.

Abstract: Apparatus for forming toner images on an image receiving member (2a-d) and transferring the toner images from the image receiving member to copy sheets comprises a transfer apparatus including a transfer intermediate member (7) having piezoelectric properties for transferring the images from an image receiving member, contained in image forming device(s) (1a-d) to the transfer intermediate member. The images are then transferred from the transfer intermediate member to copy sheets.
