Abstract

PURPOSE:To enable stable and improved toner feed, by providing a toner feed port opened toward the outer circumference of a toner carrying drum and by installing rotary blades for feeing the toner toward the port in a toner feeder. CONSTITUTION:Toner feeder 4 disposed opposite toner carrying drum 2 comprises casing 5 containing the powder toner in it, toner feed port 6 opened toward the outer circumference of drum 2, and excess toner recovering port 7 on the forward side of the rotation direction of drum 2. These feed and recovery ports 6 and 7 have slit-like opengins extended to the full length of drum 2 in its axis direction. In casing 5 rotary blades 11 are installed rotating counterclockwise around shaft 10 to feed the toner toward port 6. This permits the toner always having a uniform thickness to be carried to a stylus electrode section and an improved image to be obtained.
