A head device is for writing an electrostatic latent image on an image carrier of an image forming apparatus which is movable in a first direction. In the head device, a plurality of writing electrodes are arrayed on a 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 are brought into contact with the image carrier with a flexibility of the substrate. A head driver is disposed on the substrate. A plurality of wirings are 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. 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.
