Abstract: A developer nozzle is moved from a periphery of a wafer toward the central portion while an exposed substrate held at a spin chuck is being rotated about a vertical axis and while a developing solution is being discharged from the developer nozzle, and this way the developing solution is supplied to the surface of the wafer, the developer nozzle having a slit-like ejection port whose longitudinal direction is oriented to the direction perpendicular to the radial direction of the wafer. The movement speed of the nozzle is higher than a case where a nozzle with a small-diameter circular nozzle is used, and this enables a development time to be reduced. Further, the thickness of a developing solution on a substrate can be reduced, so that the developing solution can be saved.

The air flow in the air duct has a predetermined air pressure to hold a liquid developer within a space substantially between the developing unit and the image-bearing surface while permitting toner particles in the liquid developer deposited on the image-bearing surface to be retained by the image—bearing surface and volatile solvent to be vaporized.

Abstract: Methods and apparatus for forming on a recording medium an image whose resistance to water and light is improved and whose image quality is enhanced, with printing speed being increased due to drying of ink being accelerated. The methods include the steps of: forming a layer including resin particles on a surface of an intermediate transfer medium or on a surface of a recording medium; recording the image by jetting ink from an inkjet recording head onto the resin particle layer so that the ink is retained in cavities of the resin particle layer; and either transferring the resin particle layer from the surface of the intermediate transfer medium to a recording medium to fix the resin particle layer thereto or fixing the recording medium having the resin particle layer retaining the ink.

Abstract: A squeezing apparatus of a liquid electrophotographic printer includes a squeezing roller for squeezing out and removing the carrier from a developer which is applied on a photosensitive belt by its passive-rotational movement while being pressed into tight contact with the photosensitive belt at a certain pressure together with a squeezing backup roller, a squeezing brush selectively coming in contact with the outer circumference of the squeezing roller, for cleaning the squeezing roller by being rotated by a separate driving section, and a squeezing roller slip prevention mechanism disposed on both ends of a shaft of the squeezing roller to come in tight contact with the squeezing backup roller during the pressing of the squeezing roller, for preventing any occurrence of slip of the squeezing roller with respect to the photosensitive belt.

Abstract: An object is to provide an LED printer head in structure capable of reducing influence of a sub emission band by use of a rode lens array and thus prevent light of the sub emission band from reaching a development level, thereby achieving high quality to the contrary. The LED printer head consists of an LED array of LEDs to emit light according to an image signal, which are arrayed at the resolution pitch P of not less than 600 dpi, and a multi-lens array for forming an emission image of the LED array on a photosensitive body. Each of the LEDs of the LED array has a main emission band of an emission spectrum and another sub emission band having a peak level of not less than 0.01 as a photosensitive intensity ratio R to the main emission spectrum, and a difference D between best TCs at peak wavelengths of the main and sub emission bands by the multi-lens array is at least 0.15.

Abstract: An apparatus and method are described for supplying material to a substrate (109). The apparatus includes a member (3) having a surface with a plurality of features (8) which locate, in use, menisci of a liquid (1) supplied to the member. An actuator (4) induces mechanical vibrations within the liquid located by the features to cause liquid droplets (7) to be sprayed. Liquid (1) is supplied to the member and electrical charge is supplied to the member and electrical charge is supplied to the liquid by, for example, an electrode (14). Electrical charge or potential is also supplied to the substrate (109) so that the droplets are directed towards the substrate to deposit material thereon.

Abstract: A method and apparatus to develop electrostatic images using a mist which is substantially water and a colorant. Mist is transported from a generation station to a development station via a development electrode. Unused mist may be recycled or extracted. The mist may be size classified before development so that a consistent and desired resolution is obtained. Classification by size may be achieved by passing the mist in an arcuate path from the generation station to the development station.

The apparatus includes a liquid developing material coating flow applicator for applying a substantially uniform coating of liquid developing material to a moving surface, wherein a housing, situated proximate to the moving surface, includes a fluid transport channel having a relatively narrow-width elongated outlet port for delivering a flow of liquid developing material to the moving surface, and an air flow channel having an elongated inlet aperture located adjacent the moving surface and immediately upstream from said outlet port for applying vacuum pressure to the flow of liquid developing material for varying the profile of the coating flow to provide variation of flow stability as well as thickness. A discussion of the effects of variations in the outlet port geometry, in particular, increasing the dimension between the downstream wall and the surface to be coated, has also been provided.
