PURPOSE:To stir a developing agent effectively, by having stirring means containing at least one stirring member supported with rotatable supporting material and making the stirring member rotate and revolve. CONSTITUTION:A stirrer 5 has the 1st driving shaft 8 which is extended almost parallelly to a photosensitive drum 6 and the 2nd driving shaft 9 which is fitted to the shaft 8 rotatably, and the shaft 8 is supported to bearings 10, 11 freely rotatably at each end part area respectively. The shaft 8 is fixed with two discoidal supporting materials 12, 13 keeping at a distance with each other, and at the positions out of centers of these supporting materials, stirring means 15 including stirring materials constituted as coil-spring-shaped spiral body is supported freely rotatavely. Therefore, a developing agent is stirred effectively by rotating and revolving the stirring members. |
