摘要： Electrosensitive recording member in which blackish pattern is electrically formed on a recording layer by sparking between a needle-like electrode (stylus) and the recording layer comprising a binder and an electrically reducible metal compound. Copper iodide (CuI) is specifically included in the recording layer to increase its electroconductivity.

摘要： A thin electrically conductive material layer is provided on an electrical coloration material layer of the sheet. Upon scanning the thin conductive material layer by a recording electrode, it is possible to produce a recorded likeness of the original on the sheet by information signals as the color image of the electrical coloration material is controlled by the signals.
