摘要:
The invention makes it possible to drive a halftone image device and achieve high halftone reproduction by allowing at least one of the leading and trailing edges of a pulse width-modulated signal applied to a recording head, or forming amplitude- and width-modulated pulses, respectively, as driving pulses for placing one dot under halftone control, and changing a pulse width change of pulse width modulation in a stepwise manner, using the pulse width of the amplitude-modulated pulse as a unit pulse width. The invention intends to achieve high-voltage and high-speed pulse output and low power consumption by converting input data such as halftone image data to a voltage signal, superposing pulse voltages of opposite polarities and applying the resulting signal to a switching circuit constituting an output state in the form of a switching signal, and also makes it possible to achieve high speed and high-voltage driving by connecting at least one of equivalent two-terminal elements in series to at least one of the respective driving elements of a complementary FET driving circuit, said equivalent two-terminal elements are each put on with a current of a certain or higher value passing therethrough to show constant-voltage characteristics and put off with a current of a certain or lower value passing therethrough to become a constant resistance.

The present invention provides an electrostatic information-recording medium including an electrode layer (13) and a charge-retaining layer, in which said charge-retaining layer is formed of a laminate of a resin layer (11a) having a low glass transition temperature with a heat-resistant, insulating layer (11b), or an electrostatic information-recording medium comprising at least an electrode layer (13) and a charge-retaining layer (11) in which said charge-retaining layer (11) is formed of a polymer layer (12) containing pentafluorostyrene as a monomer component and having a weight-average molecular weight of 10,000 to 2,000,000, or which includes a photoconductive layer (44) and a charge-retaining layer (43) between a pair of electrodes (42) and (45) and is designed to carry out exposure with the application of voltage between both said electrodes (42) and (45) or apply voltage between both said electrodes (42) and (45) while exposure is carried out, thereby forming an electrostatic latent image, which is then carried on said charge-retaining layer (43) by releasing said charge-retaining layer ( 43) from said electrode 42, or which includes a charge transport layer (51) on an electrode (52) and is designed to record information on the surface of said charge transport layer (51) by toner development and then apply electrostatic charges on the surface of said charge transport layer (51) to inject said electrostatic charges into said charge transport layer through an electrically conductive layer of the toner, thereby forming electrostatic information corresponding to the toner information on said charge transport layer. Thus, the electrostatic information-recording medium can thus be improved in terms of the capability to retain electrostatic information. The electrostatic information retained in this electrostatic information-recording medium is very stable because of being accumulated in the charge-carrying layer. Also, the information can be easily reproduced in the form of information of high quality and resolution by detecting a potential difference between the electrode and the surface potential.
摘要:
A liquid development and transfer apparatus includes an application roller for supplying developing solution to an electrostatic latent image carrier surface, and an applicator for providing developing solution uniformly on the surface of the application roller. A DC bias voltage is applied to the application roller to influence development of an electrostatic latent image of the carrier, and an AC bias voltage is applied between the application roller and the applicator to prevent developer from collecting thereon as might be caused by residual potentials. After development of the electrostatic latent image for a given color on the electrostatic latent image carrier, solvent contained in the developed image layer is removed or heated, and color superimposing development is performed consecutively in similar fashion for other colors. By collectively transferring the resulting developed image to a recording paper or an intermediate transfer medium, color superimposing development can be accomplished with high accuracy without mixing of the colors of the developing solutions.

The present recording medium can also be recycled, if the information recorded on it is erased.
摘要:
An electrode 2c and a pinene polymer recording layer 2a with a molecular weight of 500 to 10000 are successively stacked on a substrate 2c, as shown in FIG. 3 . By carrying out thermal development, information electric charge that is formed on the resin surface is formed into a thermally stable frost image without decay of the information electric charge. Since no photoconductive layer is needed, when transmitted or reflected light is used to reproduce the frost image, there is no effect of the coloring of a photoconductive layer. If exposure is effected under the application of a voltage, since the depth of dimple patterns of a frost image varies in accordance with the quantity of exposure energy, tonal reproducibility is obtained. In addition, it is possible to obtain high resolution and make an original for OHP, a microfilm, a slidefilm, etc. which is of good quality and has high fidelty to the original document.
