    • A photoconductive layer is formed on the entire outer peripheral surface of a light transmissive drum, and a conductive layer is formed on the photoconductive layer and is made up of a plurality of strip-like conductive portions. Provided around the drum are a tank for storing thermo-melting ink, a blade which removes surplus ink on the outer peripheral surface of the drum, a drier for drying the ink filling the gaps between the conductive portions in the conductive layers, a platen roller which presses against the outer peripheral surface of the drum with a sheet of recording paper in between, and a light source which is provided inside the drum, facing the inner peripheral surface thereof. When the light source is selectively operated in accordance with image information, current is made to flow between the conductive portions in the conductive layer via the photoconductive layer at image recording areas, thus causing the ink filling the gap to be transferred to the recording paper.
    • 在透光性鼓的整个外周面形成光电导层,在光电导层上形成导电层,并且由多个带状导电部构成。 提供在滚筒周围的是用于存储热熔油墨的罐,用于去除滚筒外周表面上的剩余油墨的刮刀,用于干燥填充导电层中的导电部分之间的间隙的油墨的干燥器, 它们用一张记录纸压在滚筒的外周表面上,与设置在滚筒内部的面对其内周表面的光源。 当根据图像信息选择性地操作光源时,使电流在图像记录区域中经由光电导层在导电层中的导电部分之间流动,从而使填充间隙的墨水被传送到记录纸。

    • A thermal imaging device having a print surface adapted to provide localised heating to a medium comprising a thermally activatable component of an imaging forming system, the device comprising the following sequential layers:(a) a transparent or semi-transparent electrically conductive layer,(b) a photoconductive layer which when illuminated by radiation of 633 nm wavelength and intensity of 4.0.times.10.sup.6 W/m.sup.2 has a conductivity of at least 0.01 S/cm and a photosensitive ratio of at least 1.times.10.sup.3,(c) an electrically conductive layer in electrical contact with the photoconductive layer (b) and in contact with:(d) an abrasion-resistant wear layer, or,(e) a layer comprising said thermally activatable component of an image forming system;wherein the layers are constructed and arranged such that when a voltage potential is applied across layers (a) and (c) and the device is exposed through layer (a), the exposed areas of layer (b) become conductive enhancing current flow and generating heat in layer (b) at points corresponding to the exposed areas and causing localised heating at the adjacent areas of the print surface sufficient to thermally activate said component of an image forming system. The thermal imaging devices are suitable for developing thermally sensitive paper or effecting thermal transfer of a colourant, dye, toner or other image forming material.
