Abstract:
An image forming apparatus, using a recording body which comprises a recording layer, which has characteristics such that a receding contact angle of a surface of said recording layer to a liquid decreases when the surface of said recording layer comes into contact with the liquid and is heated, and the receding contact angle of the surface of said recording layer increases when the surface of the recording layer in a condition where the receding contact angle thereof has decreased is heated in air, and a base plate, which supports said recording layer, said apparatus comprising:in-liquid heating means for previously heating the entire surface of said recording layer in a condition in which the entire surface of said recording layer is in contact with the liquid;in-air heating means for heating said recording layer in air partially in accordance with image information so as to form a latent image;developing means for contacting recording agent with the surface of said recording layer, after said in air heating means has heated said recording layer, so as to develop the latent image and form a developed image; andtransferring means for transferring the developed image on the surface of said recording layer to a recording paper sheet,wherein:said recording material of said recording body contains water attraction material;said apparatus further comprises liquid applying means for applying one of water and liquid which mainly includes water to said recording surface before developing by said developing means; andsaid developing means performs developing with oil based ink.
