Abstract
A developer collecting apparatus for collecting waste developer which is generated by cleaning residual developer remained on a photoreceptor and an intermediate transfer body, includes: a waste developer container for accommodating the waste developer; a stirring member rotatably provided in the waste developer container, for stirring the waste developer; and a driving section for giving a rotary driving force to the stirring member. The driving section of the stirring member has: a driving source; a first driving force transmitting path and a second driving force transmitting path which are coupled on the driving source, for transmitting the rotary driving force to the stirring member, and when a rotational load on the first driving force transmitting path reaches a predetermined level or more, a switch-over of transmitting path can be performed from the first driving force transmitting path to the second driving force transmitting path.
