PURPOSE:To make a structure concise by constituting so that a length of a heating element for forming a magnetic latent image on a magnetic recording body, and a particle diameter of a toner are changed at every color. CONSTITUTION:When an original 1 of three colors of black, red and green is scanned optically by a light source lamp 2, a reflected light is converted photoelectrically by optical reading elements 6a, 6b and 6c, and a picture signal is stored in a storage part 7. Subsequently, as for a magnetic recordig belt 9 magnetized in one direction by a permanent magnet 10, a heat energy is given by heating elements 31a, 31b and 31c of a length corresponding to the picture signal of three colors, and a latent image 32a, a latent image 32b and a latent image 32c are formed, respectively. In this case, when a permanent magnet 14 is cooled by giving a magnetic field of the direction opposite to the permanent magnet 10, and the direction of the heat residual magnetization is inverted, a black magnetic toner of 8mu particle diameter, a red magnetic toner of 12mu particle diameter, and a green magnetic toner of 20mu particle diameter adhere to the latent image 32a, the latent image 32b and the latent image 32c, respectively. A minus charge is given by a corotron 18, and thereafter, the original is transferred to a recording paper 19 by a transfer use conductive rubber roll 20, and discharged after the fixing process is ended. |
