Abstract:
1. An image forming device, comprising: a toner bearer including plural linear electrodes aligned at a first regular pitch in a crosswise direction of the toner bearer, configured to cause toner to fly along the surface of the toner bearer between the plural linear electrodes upon application of a pulse voltage thereto to form a floating toner layer; and a substrate including plural hole-electrode combinations arranged in a longitudinal direction of the linear electrodes, each formed of a through-hole and a hole-adjacent electrode located close to the through-hole, wherein the floating toner layer is formed in an area facing the through-hole, and toner passes through only the through-holes facing a desired image from the floating toner layer upon application of a record-on voltage for recording a dot or a record-off voltage for not recording a dot, and wherein the plural hole-electrode combinations arranged in a longitudinal direction of the linear electrodes are arranged in lines at a second regular pitch in a crosswise direction of the toner bearer, and the second regular pitch is an integral multiple of the first regular pitch.
