ABSTRACT:
A process of the present invention forms an image on a recording medium, the surface of the recording medium having a characteristic in which a receding contact angle decreases when the recording medium is heated under a condition in which a solid material is in contact with the surface of the recording medium. The process includes the following steps (a) through (d) of: (a) bringing a solid member into contact with the surface of the recording medium; (b) selectively heating the surface of the recording medium, so that the surface of the recording medium is heated under a condition in which the solid member is in contact with the surface of the recording medium; (c) cooling the recording medium under the condition in which the solid member is in contact with the surface of the recording medium; and (d) separating the solid member from the surface of the recording medium. As a result, a receding contact angle on an adhesive area is decreased, and a latent image corresponding to the adhesive area is formed on the surface of the recording medium.
