Abstract:
1. A head device, for writing an electrostatic latent image on an image carrier of an image forming apparatus which is movable in a first direction, the head device comprising: a flexible substrate; a plurality of writing electrodes, arrayed on the substrate in a second direction perpendicular to the first direction to form a plurality of electrode arrays which are arranged in the first direction, the writing electrodes being brought into contact with the image carrier with a flexibility of the substrate; a head driver, disposed on the substrate; and a plurality of wirings, extending in the first direction to connect the head driver and the respective writing electrodes to supply writing voltages from the head driver to the writing electrodes, wherein at least one of the wirings extended through one of the writing electrodes in one of the electrode arrays is placed between adjacent ones of the writing electrodes in another one of the electrode arrays.
