Abstract
A transfer-type electrothermographic recording method comprising the steps of uniformly charging an electrothermographic recording layer 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 by applying digital thermal signals which correspond to an original image, developing the latent electrostatic image with a toner of which polarity is the same as or opposite to the polarity of the electric charge of the latent electrostatic image to form a toner image, transferring the toner image to a receiving medium, and fixing the toner image transferred on the receiving medium; and a recording medium for use with the transfer-type electrothermographic recording method, comprising the above electrothermographic recording layer.
