PURPOSE:To enable the handwriting input of a toner image to an image display sheet by installing a magnet into a ball made of a metal and communicating a space in a drum section and a space in a front end while housing a conductive magnetic toner. CONSTITUTION:A ball 2 made of a metal has a magnet 5 such as a ferrite magnet as a core body on the inside. The upper section of the surface of the ball 2 is supplied with a magnetic toner 3 filled into a drum section 1b by the magnetic force of a magnet 5, and the magnetic toner 3 adheres and exists on said surface at all times. A ground wire 6 connected to the ball 2 made of the metal is grounded through a cap 4. The toner 3 brought into contact with the ball 2 made of the metal adheres on the surface of a dielectric layer II by coulomb force. When the ball 2 made of the metal is brought into contact and handwriting is conducted, the ball 2 is rotated, and the novel toner 3 is fed at all times, thus continuously attaching the toner 3 on the surface of the dielectric layer 11. Accordingly, a toner image is input by handwriting. |
