In a method for transferring information in a form of electron beam, an electron beam detector detects the electron beam, and emission of the electron beam from a predetermined electron beam source is controlled in accordance with a signal from the detector upon detection of the electron beam. A deflection electrode is also used to deflect the electron beams according to an electric or magnetic field to perform charge shifting, logical additions, logical multiplications, image formation, and the like.

A fluid ink which is substantially nonadhesive but can be imparted with an adhesiveness on application of an energy such as electrochemical energy or heat energy, is obtained by impregnating a crosslinked substance such as guar gum or polyvinyl alcohol compound with a liquid dispersion medium such as water. The fluid ink, preferably formed into a layer in advance, is supplied with a pattern of energy to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the energy pattern applied.

A printing process using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the printing process, the ink is subjected to a pH change to be provided with an adhesiveness to a desired depth, and the resultant adhesive ink is supplied to a printing plate having a pattern of ink receptibility to form thereon an ink pattern corresponding to the ink receptibility pattern. The ink pattern is then transferred to a transfer-receiving medium such as plain paper to form thereon a recorded image. In the above-mentioned printing process, a uniform thin ink layer can be supplied to the printing plate by chemically regulating the amount of the ink to be supplied.

Charging device

An ink which can be imparted with an adhesiveness on application of an electric current is obtained by impregnating a crosslinked substance such as guar gum or polyvinyl alcohol compound with a liquid dispersion medium such as water. The ink is supplied with a pattern of energy to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the energy pattern applied. The ink further comprises a buffer action-imparting substance and is excellent in storage stability and stability of performances during a continuous use.

Image recording ink

An image recording and/or reproducing apparatus including a recording unit having a recording driving mechanism for recording a plurality of images in the form of electrostatic pattern on different regions of a photosensitive member, a reading unit having a beam source and capable of scanning the photosensitive member by an electron beam so as to convert the recorded pattern into electric signals, and a connecting member for connecting the recording unit and the reading unit without causing any change in the states of these units. This apparatus makes it possible to record and/or to reproduce images with a high image quality. The connecting member includes a container accommodating the recording unit and the reading unit. Alternatively, the connecting member is adapted to keep a portion of the recoding unit and a portion of the reading unit in close contact with each other.

Image recording and/or reproducing apparatus

An optical modulation device includes: a ferroelectric liquid crystal disposed between a pair of substrates; provision for applying an alternating voltage sufficient to render the ferroelectric liquid crystal turbid; and provision for superposing a DC voltage on the alternating voltage. A portion of the ferroelectric liquid crystal rendered turbid through the application of an alternating voltage is selectively caused to have an increased transmittance when superposed with a DC voltage.
