PROBLEM TO BE SOLVED: To make it difficult to suck waste toner from a waste toner receiving pipe for supporting a carrying screw by using a suction jig. SOLUTION: A sheet-like checking member 49 is arranged in the waste toner receiving pipe 61 for supporting the carrying screw 47. As shown in the figure (a), the waste toner 48 is easily put into a collecting bag 46 through the carrying screw 47, but as shown in the figure (b), in the case of sucking the waste toner 48 into the collecting bag 46 by the suction jig, etc., the checking member 49 sticks to the waste toner receiving pipe 61 so as to check the suction of the waste toner 48, then, the waste toner 48 is not easily sucked. |
