PURPOSE:To make it possible to miniaturize the titled apparatus by reducing a number of wirings, in an image recording apparatus using toner, by dividing signal electrodes into a plurality of groups each comprising the same numbers of electrodes to which photoconductive elements are added while successively irradiating said groups with light to drive the same in a divided state. CONSTITUTION:When signal voltage is applied to signal electrodes 1' from a character generator 2 and, at the same time, said electrodes are irradiated with light from a light source 13, a photoconductive substance 11 is converted to a conductor and toner 7 is adhered to a recording body 8 in which charge is induced through the nibs of the toner 7 formed on the signal electrodes 1' but, when the light of the light source 13 is blocked, the photoconductive substance 11 functions as an insulator and the toner 7 is not adhered to said recording body 8. A large number of the signal electrodes 1' constituted as mentioned above are divided into a plurality of groups comprising the same numbers of electrodes and the light is successively irradiated from the light source corresponding to each group and the signal voltage of the character generator 2 is successively applied to the electrodes in each group through the signal wire common to the groups to form an image. by this method, a number of wirings can be reduced to a large extent and no inverse flow of a current is generated and a sharp image can be formed. |
