The surface of the recording medium has a characteristic which a receding contact angle becomes smaller when the recording medium is brought into contact with liquid and it is in the heated status. The contact material is selected from a liquid, a vapor or a liquid under conditions of a temperature lower than a temperature at which the receding contact angle of the recording medium starts to decrease. An area having the receding contact angle corresponding to a temperature of the recording medium obtained by selectively heating the surface of the recording medium in accordance with image information in formed, as latent image, on the surface of the recording medium.
