Abstract
A multi-stylus head comprising a plurality of segmented electrodes aligned in at least one row and multiple styli aligned in a row and grouped corresponding to the segmented electrodes. The multi-stylus head is capable of forming electrostatic latent images on a dielectric layer of a recording material by applying a voltage to the segmented electrodes and the multiple styli. In order to prevent the image density of the electrostatic latent images from becoming uneven in the direction normal to the recording scanning direction, the grouped multiple styli are shifted relative to the segmented electrodes in the direction of the recording scanning direction.
