A printing system is disclosed for thermal transfer printing onto a surface of a substrate. The system comprises a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head via the rear side of the transfer member to selected regions of the imaging surface to render particles coating the selected regions tacky, and a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of the particles that have been rendered tacky.

There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.

Provided is conductive carbon which gives an electric storage device having a high energy density. This conductive carbon is characterized in having a hydrophilic solid phase component, where the ratio of the peak area of an amorphous component band in the vicinity of 1510 cm.sup.1 against the peak area in a range from 980 to 1780 cm.sup.1 in a Raman spectrum of the hydrophilic solid phase component is within a range of 13 to 19%. When performing a rolling treatment on an active layer including an active particle and this conductive carbon formed on a current collector during manufacture of an electrode of an electric storage device, the pressure resulting from the rolling treatment causes this conductive carbon to spread in a paste-like form and increase in density while covering the surface of the active particles, the conductive carbon being pressed into gaps formed between adjacent active particles and filling the gaps. As a result, the amount of active material per unit volume in the electrode obtained after the rolling treatment increases, and the electrode density increases.
