ABSTRACT:
A transfer-type electrothermographic recording method is disclosed, which comprises the steps of uniformly charging an electrothermographic recording layer to a predetermined polarity, which exhibits chargeability A at room temperature and chargeability B above room temperature, where the chargeabilities A and B are in the relationship of A>B.gtoreq.0; forming a latent electrostatic image on the charged surface of the electrothermographic recording layer by applying thermal signals which correspond to an original image to the side opposite the charged surface of the electrothermographic recording layer; and developing the latent electrostatic image with a toner of which polarity is the same as or opposite to the polarity of the latent electrostatic image to form a toner image. This transfer-type electrothermographic recording method may further comprise a step of transferring the toner image to a receiving medium; and a step of fixing the toner image transferred onto the receiving medium. An apparatus for the above transfer-type electrothermographic recording method is also disclosed.
