<P>PROBLEM TO BE SOLVED: To provide a developing unit in which excellent toner having enhanced flowability is uniformly supplied by mutually and sufficiently stirring and mixing the toner at the center part and both end parts of a developing roller by improving the flowability of toner at both end parts of a stirring means in a toner container and also the occurrence of a defective image is suppressed by reducing vibration caused by the fluctuation of a load when the stirring means is rotated. <P>SOLUTION: The developing unit 10 is provided with: a toner container 1 equipped with the stirring means 2 to stir the toner 3 and also to supply the toner to the developing roller 6; and the developing roller 6 to visualize an electrostatic latent image on the surface of a photoreceptor 8 by electrifying the toner 3 on the surface of the developing roller and feeding the toner to the surface of the photoreceptor 8 as a thin layer, wherein the stirring means 2 is provided, in the toner container 1, with a rotary shaft in parallel with the rotary shaft of the developing roller 6 and three or more elastic sheet blades whose one side is stuck to the rotary shaft of the means 2 and whose opposed other sides are formed as free ends. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
