<P>PROBLEM TO BE SOLVED: To effectively use all toner by making it possible to loosen toner solidified in a supply path, so as to prevent an erroneous decision that toner is empty. <P>SOLUTION: Both ends of the shaft 29a of a loosening member 29 are inserted through holes (not shown) in the respective sidewalls opposite to each other of a developing tank 20. The loosening member 29 is supported to freely move in a direction where the loosening member passes through the supply path 20a, that is, the direction of the shaft 29a. When the toner is solidified in the supply path 20a, the loosening member 29 is in such a state that it is inserted into the toner mass of the supply path 20a. Thus, when the operating knob 29b of the loosening member 29 is operated to repeatedly reciprocate the shaft 29a and respective film pieces 29c of the loosening member 29 in the direction of the shaft 29a, the toner mass of the supply path 20a can be loosened. <P>COPYRIGHT: (C)2007,JPO&INPIT |
