Abstract: In a wet recording apparatus comprising: an image bearing structure; a developing solution prepared by dispersing charged color material particles in a dispersion medium; an ion generating unit; and ion current control units, the developing solution is applied to the image bearing structure to form a developing solution layer thereon, the ion current controlling unit operates to cause ions produced by the ion generating unit to stick selectively to the surface of the developing solution layer, to form a color material image on the image bearing structure, and the color material image is transferred, as a toner image, onto a recording sheet.

Abstract: An ink jet print head is provided having a nozzle forming substrate with a plurality of nozzles formed therein. Vibrators formed on a piezoelectric transducer disposed within the ink jet print head opposite the nozzles are independently drivable. A first gap is formed between the nozzle forming substrate and a vibrator in a region adjacent the nozzles. A second gap is formed between the nozzle forming substrate and a vibrator at a region away from the nozzles having a different dimension than the first gap.

Abstract: A combination toner for xerographic image formation having conductive portions and insulating portions is provided. The conductive portions function to accumulate a charge in the toner particles and the insulating portions function to lengthen the period of discharge of the accumulated charge. The toner can be either magnetic or non-magnetic and improves image formation and transfer.
