Repeating device, telephone set, and recording medium

An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.

A powder composition containing a powder of a modified polymer having a recurring unit containing at least one carboxyl group, the carboxyl groups of part of the recurring units being in the form of a salt with an aliphatic amine having at least 6 carbon atoms, and a powder of a surfactant. The powder composition is used for forming an image on a printing medium, in which method the composition is applied over a surface of a transfer medium to form a layer of the powder. An image of a liquid ink capable of dissolving or swelling the powder is then formed on the layer so that the viscosity of the liquid ink increases when contacted with the powder. The image on the transfer medium is contacted with the printing medium so that the image is transferred to the printing medium.

A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc. Thereafter, the transfer paper sheet is discharged onto a paper discharging tray. Accordingly, it is possible to provide a method and an apparatus for regenerating and reusing the transfer paper sheet by removing the toner therefrom without damaging paper fibers.

After a row address and a column address are supplied to a dynamic RAM in response to a row address strobe signal and a column address strobe signal, respectively, a high impedance state is maintained for column address access time period after the fall timing of the column address strobe signal, thereafter data is outputted to a data bus, and the high impedance state of the data bus is quickly resumed after the rise timing of the column address strobe signal. If different column addresses of RAM at the same row address are successively read, data are read and outputted to the data bus in response to a change only in the column address strobe signal, and thereafter, even after the high impedance state of the data bus is quickly resumed, a data value is held by the data bus until the dynamic RAM outputs the data.

Storage reading apparatus

This invention provides a method for using paper repeatedly by flaking and removing an image from the paper, even if the image has been touched up on the paper with handwriting, and a preferable printing tool used in the method. The method includes the steps of touching up the image on the paper with the printing tool containing a main component of a colored thermoplastic resin particle and being formed into a stick shape by solidifying the resin particle alone or with binder resin sticking to the resin particle. The image can be formed on the paper with a liquid-applying type of printing tool having a liquid container containing a resin dispersion liquid being formed by dispersing the resin particle in a solvent. Regenerating of the paper by removing the touched-up image from the paper comprises the steps of wetting the paper through a treatment liquid such as water, and while heating the resin particle of the image, adhering the resin particle to a flaking member having a greater adherent force to the resin particle than the adherent force between the resin particle and a surface of the paper so as to flake and remove the resin particle from the surface of the paper.

In a method and an apparatus for discriminating real securities from copies thereof produced by an electrophotographic copier using a toner, a heating member heated to a temperature above 50.degree. C. and below 250.degree. C. is brought into contact with a printing to see if an image on the printing changes or if any deposit is present on the heating member. Whether or not the image of the printing is formed by a toner whose major component is a thermoplastic resin, is determined on the basis of the result of the above decision.
