Abstract
An image forming apparatus includes an image bearing member, a developing apparatus, a driving device, an airflow space portion, a duct, and, a drawing fan. A driving-force transmission member, the driving device and the airflow space portion are disposed on a side on which a developer container faces the image bearing member. The driving-force transmission member, the driving device, the duct and the drawing fan are disposed on one end side of a developing rotary member in a rotation-axis direction of the developing rotary member. The duct is disposed underneath the developer container, formed from the side on which the developer container faces the image bearing member to a side opposite to the side on which the developer container faces the image bearing member. The drawing fan is disposed on the side opposite to the side on which the developer container faces the image bearing member.
