PURPOSE:To remove only image-forming elements of a non-image forming part completely, thereby obtaining a sharp recording image by providing a means to give prearranged magnetic and thermal energies and remove from a suspending member the image-forming elements in which magnetic characteristics change in accordance with an image signal. CONSTITUTION:Ink which is not magnetically oriented in a recording means 4 stands at a softening point temperature of approx. 60 deg.-80 deg.C and that which is magnetically oriented shows a rise of approx. 150 deg.C or higher. Then if capsule ink 8 which is applied a magnetic field by a recovery magnet 5e is heated to 100 deg.C by means of a heater 20 and a fan 21, the magnetically unoriented ink 8 is strongly attracted to the surface of a drum 1 because the viscosity decreases and a magnetic material moves around freely in cores 8a, 8b, generating an alternating magnetic field. In the meantime, the magnetically oriented ink 8 jumps from the drum 1 to a recovery belt 5a, because the viscosity does not decrease and a repulsive force is applied. This jumping ink 8 is attracted to the recovery belt 5a by a static electric force, then it is recovered by a waste toner case 5j through a magnet roller 5h and a screw 5i. |
