Abstract

A process for forming a dot image on a recording medium, a 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 liquid is in contact with the surface of the recording medium. The process includes the steps of forming a latent image having a plurality of dots, and developing the latent image by a liquid recording agent relative to which the recording medium is moved in a moving direction, wherein each of the dots making the latent image has a triangular shape becoming narrower in a direction opposite to the moving direction. The above step of forming the latent image includes the steps of bring a liquid into contact with the surface of the recording medium, and selectively heating an area on the surface of the recording medium, the area corresponding to each of dots making the latent image, so that the area having the receding contact angle whose value corresponds to a temperature of the heated area becomes each of dots making the latent image.
