Title: Waste toner recovery container and image forming apparatus using the same
Inventor: NINOMIYA HIROMICHI
IPC: G03G21/10
Filed: 2007-06-27
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrences of damages and malfunctions caused by an abnormal state in a conveying means in a waste toner recovering container, with the result that waste toner cannot be conveyed normally, and consequently a waste toner conveying means in the main body in the image forming apparatus is locked.  <P>SOLUTION: If a waste toner conveyance screw 38 is damaged and an abnormal state is detected, for example, the waste toner conveyance screw 38 is broken by caking of waste toner entering a gap between a bearing 37 and the waste toner conveyance screw 38, a coupling 34 is pressed against a spring 35 and moves to the main body driving side. Since the coupling 34 moves to the main body driving side, the pressure of the spring 35 pressing an abnormal detecting member 41 decreases, with the result that an abnormal detecting means cannot maintain its attitude and cannot presses a detection sensor 40 any longer. Accordingly, an abnormal state is detected.  <P>COPYRIGHT: (C)2009,JPO&INPIT
