摘要:
In an electrophotographic printing apparatus for printing using a three level printing method, there are provided a first color data memory and a second color data memory which memorize the pixel data of every color sent from host equipment, such as a computer connected to an electrophotographic printing apparatus, and by the use of image recognition equipment for judging whether pixel information is part of what image, exposure information with exposure equipment is determined so that the electric current flowing into electric current source and electric current source is changed. With such an arrangement, the exposure data for every color to be printed is created on the basis of the recognized result the part of a particular image that the pixel data shows, and the color image of the line-width in accordance with data sent from the host equipment to the electrophotographic printing apparatus can be actually printed by controlling the exposure beam diameter.

A color electrophotographic printer having a printing process which records a toner image of one color or two colors in a pixel by one exposure. The color electrophotographic printer includes a memory which stores exposure data corresponding to respective pixels of input data of an image, a photosensitive body and at least one charger which charges the photosensitive body. At least one exposing machine exposes respective pixels on the photosensitive body based on the exposure data and a developing machine develops toner of one color or two colors in the exposed respective pixels and forms a toner image. A transfer machine transfers the toner image onto a printing medium and a fixing machine having a belt which fixes the transferred toner image on the printing medium. The belt is controlled so that a relative speed difference occurs between the printing medium and the belt at a position along the belt at least when the developed toner of two colors in one pixel of an image of the printing medium is fixed.

A high-speed image forming method and apparatus is capable of directly controlling a toner by the force of an energy beam. Selected toner particles in a mass of toner adhering to the surface of a transparent drum are irradiated with a laser beam emitted by a laser disposed within the transparent drum and controlled for scanning according to image information. The laser beam separates the selected toner particles from the transparent drum by the force it produces on the particles, and then the separated toner particles are moved to a paper sheet by the force of an electric field produced by a developing electrode. Each toner particle need only be irradiated with the light for a comparatively short period of time, so that an image can be formed at high speed.

An ink jet recording head has a plurality of ink-discharge electrodes and control electrodes and an opposed electrode arranged at a fixed spacing and grounded. A pulse voltage with a reversed polarity is applied to the control electrodes in synchronization with the superimposition of the pulse voltage on a bias voltage applied to the ink-discharge electrode when the ink is discharged. As a result, an ink jet recording apparatus, which can decrease the pulse voltage needed to discharge the ink, is provided with a simple configuration.

An inkjet recording apparatus comprises a main body, a print head, and a cable. The main body includes an ink container for storing ink, an ink supply pump for supplying the ink, and an operation control section. The print head includes a nozzle for expelling the ink supplied from the main body as ink particles, charging electrodes for charging the ink particles, deflecting electrodes for deflecting the charged ink particles, and a gutter for collecting ink particles that have not been used for printing. The cable includes an ink supply path through which the ink is supplied from the main body to the print head, an ink collecting path through which the ink particles collected in the gutter are returned to the ink container, signal lines interconnecting the operation control section and the print head. An ink collecting pump for transferring the ink particles collected in the gutter to the ink container is disposed in the print head.

A production device to produce an organic EL display includes a solution in which a light emitting material is dissolved, and a flying electrode to receive solution from the container. A voltage is applied between the tip of the flying electrode and an electrically conductive material of an organic EL substrate to form an electrostatic field, and the tip of the flying electrode and the organic EL substrate are shifted relative to one another in at least one of a perpendicular direction and a horizontal direction. With this arrangement, the solution is formed into a stringy beam from the tip of the flying electrode to it fly onto the organic EL, substrate, thereby injecting the solution into a concavity formed and surrounded by banks on the organic EL substrate, and forming red, green and blue light emitting layers.
