摘要： An electrostatic latent image is formed by the Carlson process, etc. on a base (photosensitive body) to develop the electrostatic latent image by a solidification developer in which coloring agent particles are dispersed into a dispersion medium in a solid state at an ordinary temperature and adapted to reversibly repeat fusion by heating at about 30.degree. C. at a temperature above a melting point and solidification by cooling, thus to form a developer picture. Thereafter, the base and a transferred body are caused to be subjected to pressure-contact and heating process to fuse the dispersion medium at a pressure-contact and heating temperature more than the melting point of the dispersion medium to subsequently cool the dispersion medium down to a temperature less than the melting point to peel the transferred body to transfer the developer picture onto the transferred body. Alternatively, the dispersion medium is softened at a pressure-contact and heating temperature set so that this temperature falls within a range where it is not above the melting point to subsequently peel the transferred body to transfer the developer picture onto the transferred body. On the surface of a recording paper, a resin layer compatible with a dispersion medium of a developer may be formed.

摘要： A developer for electrostatic electrophotography which comprises a composition of colorant particles, an electric charge supplying agent and a resin binder dispersed in a dispersion medium. The resin binder is a copolymer which has a polyoxyethylene units at side chains thereof, so that the interaction with the electric charge supplying agent is improved. The resultant developer ensures good resolution, gradation and fixing property and is suitable for wet development to give high-quality images. When the copolymer used as the resin binder has styrene units therein, its solubility in the dispersion medium is improved. The developer is either liquid or solid depending on the type of dispersion medium.

摘要： An ink-jet printer and a drive method for driving a recording head of an ink-jet printer are provided for controlling a size and a velocity of an ejected ink droplet. The ink-jet printer includes a droplet outlet orifice through which an ink droplet is ejected, an ink chamber communicating with the outlet orifice, an ink feed duct for feeding ink to the ink chamber, and a piezoelectric element for expanding and contracting the ink chamber in response to an applied voltage. A process for ink ejection includes a first step in which a meniscus in the outlet orifice is retracted towards the ink chamber by expanding the ink chamber, a second step in which the meniscus is moved towards the orifice by filling the chamber with ink, and a third step in which an ink droplet is ejected by contracting the ink chamber. The size and the velocity of the ink droplet ejected in the third step are controlled by controlling a position and a velocity of periodic travel of the meniscus at a start point of the third step.

摘要： On a liquid discharge head including an ink discharge surface (6) having rows of ink discharge holes (13) each for discharging different colors of ink, a cleaning roller (7) formed of a cylindrical elastic material touching the ink discharge surface (6) is moved relative to the ink discharge surface (6). This movement causes the pressure inside the ink discharge holes (13) to change and, as a result, the ink (15) inside the ink discharge holes (13) is absorbed. In this way, a ink discharge head, a method for cleaning thereof, and a ink discharge apparatus that do not damage the ink discharge surface (6) with the ink discharge holes (13) and that have improved effectiveness of cleaning the vicinity of the ink discharge holes (13) are provided.

摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of an ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.
