<P>PROBLEM TO BE SOLVED: To solve the problem that a developer tank provided to an image forming apparatus removes developer remaining inside by making the air flow inside for recycle, however, in that case, a place to which the air can not easily flows occurs and it is hard to remove toner remaining at the place. <P>SOLUTION: In the developer tank 35, the flow of the air toward one direction is formed inside by forming a developer filling port 51 used when the developer is filled and a ventilation port 56 at a position opposite to the filling port 51 through an internal space for storing the developer, sucking the internal air from the filling port 51 and performing cleaning processing so that the external air flows in from the ventilation port 56 in that case. <P>COPYRIGHT: (C)2007,JPO&INPIT |
