ABSTRACT:
A process for forming a dot image on a recording medium which has a surface having a characteristic in which a receding contact angle decreases when the recording medium is heated in a condition where the recording medium is in contact with a liquid. The process includes in an arbitrary order the following steps (a) and (b) of: (a) selectively heating the surface of the recording medium so that one or a plurality of heated areas are formed on the surface of the recording medium in accordance with image information, the size of each heated area being controlled in accordance with the image information; and (b) bringing a liquid to the surface of the recording medium, wherein the receding contact angle of each heated area decreases so that a latent image corresponding to one or the plurality of the heated areas is formed on the surface of the recording medium. An apparatus for forming a dot image operates in accordance with the above process.
