Filed: 1985-05-01
Abstract: PURPOSE:To obtain a record with high image quality by disposing the plural through-holes of an ion current control head to part of the approximately concentrical cylindrical face of a roller facing the same. CONSTITUTION:The potential of an electrode 44 is waved above and below in accordance with image information on the basis of the potential of an electrode 42. An electric field in the direction from the electrode 42 toward the electrode 44 is formed in the through-holes 40 when the electrode 44 is at an L level and therefore only the ions of the negative polarity are irradiated through the holes 40 to the rear surface of a recording member 1. The direction of the electric field formed in the holes 40 is reversed and only the positive polarity ions are irradiated to the rear surface of the member 1 when the electrode 44 is conversely at an H level. A toner layer 12 is transferred only on the surface of the member 1 in the region (picture element) irradiated with the ions of the polarity reversed from the polarity of the toner layer when the ions of the polarities corresponding to the image information are irradiated to the rear of the member 1 in the above-mentioned manner. The toner image corresponding to the image information is thus directly formed on the surface of the member 1.
