Process for forming image on novel recording medium

A process for forming an image on a recording medium, a surface of said recording medium having a characteristic in which a receding contact angle decreases when said recording medium is heated under a condition in which a solid material is in contact with the surface of said recording medium, said process comprising the following steps (a) through (d) of:

• (a) bringing a solid member into contact with the surface of said recording medium;
• (b) selectively heating the surface of said recording medium, so that the surface of the recording medium is heated under a condition in which said solid member is in contact with the surface of the recording medium;
• (c) cooling the recording medium under the condition in which said solid member is in contact with the surface of the recording medium;
• and
• (d) separating said solid member from the surface of the recording medium,
• whereby a receding contact angle on an adhesive area which is an area heated by said step (b) on the surface of said recording medium is decreased and reaches a value corresponding to a temperature at which said adhesive area is heated, and whereby a latent image corresponding to said adhesive area is formed on the surface of said recording medium.
