发明名称 Image forming device and image forming apparatus
摘要 An image forming device, including a toner bearer including plural linear electrodes located at a first regular pitch in a crosswise direction thereof, flying a toner on the surface thereof between the plural linear electrodes with 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 a toner passes through only the through-holes facing a desired image from the floating toner layer with a record on or off voltage, and the plural hole-electrode combinations are lined 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.
