ABSTRACT:
An image forming apparatus having a high toner containing efficiency of a waste toner-collecting container is provided. Piled toner is broken by an vibrating imparting operation and at the same time, a toner feeding member such as a feeding screw disposed inside the toner-collecting container is rotated by changing a reciprocating operation by the vibrating impartment to a rotational operation in a direction. As a result, the piled toner which cannot be completely broken by the vibrating imparting operation is broken and fed, so that driving noise is reduced and the toner containing efficiency is improved.
