ABSTRACT:
An ink transfer medium for toner is disclosed, comprising the following layers, in this order: a heat-generating resistive layer heated by input of electrical signal, a conductive layer, and an ink release layer having a toner layer on it, an adhesion from 0.2 g/mm to 40 g/mm as measured by the 90.degree. peeling off method and consisting of a viscoelastomer having a critical surface tension of 35 dyne/cm or less. It can be re-inked by attaching toner to the portions of the ink transfer medium from which the ink has been removed, using toner held in a toner holding means.
An ink transfer process for toner is also disclosed, wherein an ink transfer medium having toner layer formed on the above described ink release layer is used and the toner layer contacts the recording medium under pressure, while a recording head contacts the anisotropic conductive layer of the ink transfer medium, so that an electrical signal is input and then toner fused by heat generated by the heat-generating resistive layer is transferred to the recording medium.
