Developing apparatus

摘要

A developing apparatus includes a developer container. An agitating member agitates developer contained in the developer container. A drive transmitting member transmits power to the agitating member by engaging a rotary shaft of the agitating member. A bearing is adapted to rotatably hold the drive transmitting member to the developer container. The bearing includes a notched portion having a rotation regulating and positioning function to prevent the bearing from being dislodged from the developer container.
