Abstract
An image recording method and an image recording apparatus using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the image recording method, the ink is subjected to a pattern of pH change to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the pH change pattern.
Claims16
An image recording method, comprising:
- providing an ink which is substantially non-adhesive and capable of being imparted with an adhesiveness when subjected to a pH change;
- causing a pattern of pH change corresponding to a given image signal on a layer of said ink formed on an ink-carrying member to form an adhesive pattern of the ink corresponding to the image signal;
- and
- transferring the adhesive pattern of the ink to a transfer-receiving medium to form thereon an ink pattern corresponding to the adhesive pattern.
An image recording apparatus, comprising:
- an ink-carrying member moved along an ink contact position for carrying thereon a layer of an ink which is substantially non-adhesive but capable of being imparted with an adhesiveness when subjected to a pH change;
- a transfer-receiving medium moved along the ink contact position so as to contact the ink layer formed on the ink-carrying member at the ink contact position;
- and
- means for supplying a pH modifier to the ink layer to cause a pattern of pH change on the ink layer;
- whereby a part of the ink on the ink-carrying member imparted with an adhesiveness corresponding to the pattern of the pH change is selectively transferred to the transfer-receiving medium.
