摘要： An electrophotographic apparatus utilizes solid developers of a plurality of colors for developing an electrostatic latent image. The solid developers are solid at normal temperature and are changed into liquid by heating. The liquid developers are supplied to the static latent image and develop it. The solid developers of a plurality of colors are accommodated within a single container in a predetermined order so that the electrophotographic apparatus can be simplified and made inexpensive.

摘要： An image forming material is provided in which a developer container containing a developer consisting of an electrically insulating organic material which is solid at ambient temperature and which may be liquefied on heating, and wherein colorant particles are dispersed in the material, is made as one with a photosensitive base on which to form an electrostatic latent image. With such image forming material, the developer required in the developing process is incorporated in the photosensitive base to permit image formation and storage by the electrophotographic process to be performed as easily as in so-called instant photography. When the outer size of the image forming material or that of the separated photosensitive base is of the 35 mm format slide size, the imaging material or the base may be attached directly to a slide projector or the like to permit the image information to be easily seen.

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： An electrophotographic process uses a developer in which the colorant is dispersed in an electrically insulating organic material being solid at room temperature and liquified by heating. The developer is superior in ease of handling and capable of producing stable images at all times. An electrostatic latent image is wet developed by the developer. For recording and preserving the developed image, it is transferred to a transfer substrate. The developed image is transferred by contact of a photoconductor with the transfer substrate, or by peeling a film from a photoconductor.

摘要： A wavelength multiplexed optical recording material is disclosed wherein a photosensitive material including substituted porphine, such as tetra(pentafluorophenyl) porphine or tetra(4-methoxyphenyl) porphine, is uniformly dispersed into an optically transparent dispersion medium. When such wavelength multiplexed optical recording material is cooled to a temperature of liquid helium and irradiated with a laser beam, a large number of holes of narrow width are formed in an inhomogenous absorption band under the phenomenon of photochemical hole burning. As compared to unsubstituted porphine, the above porphine derivatives give an improved recording sensitivity and narrow hole width.

摘要： A liquid crystal is dropped on one end portion of a bottom substrate that is coated with a sealing material in an outer peripheral portion. After a top substrate is laid on the bottom substrate, the liquid crystal is expanded from the one end portion of the bottom substrate toward the other end portion. If necessary, an air ejecting opening is formed in the sealing material at a position located in the other end portion of the bottom substrate. The surfaces of the top and bottom substrates may be formed with grooves for accommodating an excessive part of the liquid crystal at positions inside the sealing member. As a result, no air bubbles remain in the liquid crystal even if the charging of the liquid crystal is performed at the atmospheric pressure.

摘要： An ink sheet (3) is wound around rollers (6), and a recording sheet (4) is placed with a space (d) between the ink sheet (3) and the recording sheet (4) and is advanced. The thickness of the space (d) is a value in the range of 1 to 100 .mu.m. The ink sheet (3) is irradiated with a laser beam (L) emitted by a laser (5) to transfer the dye contained in a dye layer formed on the ink sheet (3) from the ink sheet (3) to the recording sheet (4) for printing. The dye layer of the ink sheet (3) is replenished with the dye (30, 30A) heated and fused by a heater (9) by a dye supply unit (7) at a position other than a position where the ink sheet (3) is irradiated with the laser beam (L). Since the ink sheet and the recording sheet are held with the space (d) having a thickness in the range of 1 to 100 .mu.m, the dye once transferred to the recording sheet is not transferred from the recording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed. Since the dye layer of the ink sheet is replenished with the dye, the ink sheet can be repeatedly used, so that no waste is produced.
