<P>PROBLEM TO BE SOLVED: To provide an inexpensive developing device capable of properly disentangling the aggregation of toner, with a simple and easy structure. <P>SOLUTION: An agitator 5 is configured so that stirring portions 52 consisting of a U-shaped pipe are connected at both end portions 53 of the stirring portions 52 on both sides, around a rotating shaft 51 and rotated in the direction of an arrow D in accordance with the rotation of the rotating shaft 51, to send out toner T around the stirring portions 52 to the vicinity of a supply roller 3, while stirring the toner T. In the stirring portions 52, air ejection holes 54 are formed at predetermined intervals, compressed air supplied through the rotating shaft 51 being hollow is ejected from the air ejection holes 54 of the stirring portions 52 connected through the rotating shaft 51 and both end portions 53, to disentangle the aggregation of the aggregated toner T, and air is passed between the toners to improve the flowability of the toner. <P>COPYRIGHT: (C)2008,JPO&INPIT |
