Abstract
An image forming apparatus is provided which can reduce occurrence of unusual noise. The image forming apparatus includes a driving motor configured to drive a developer bearing member and a control unit which can control the driving motor between a first driving speed and a second driving speed higher than the first driving speed. In a case where the first driving speed is equal to the driving speed of the image forming operation, the control unit controls the driving motor to drive at the second driving speed while an unsealing operation is being performed.
