Image forming apparatus

An image forming apparatus comprising:

• an image bearing member;
• an exposure apparatus configured to expose the image bearing member for forming an electrostatic latent image on the image bearing member;
• a developing apparatus comprising:
• a developer container configured to accommodate developer that contains toner and carrier,
• a developing rotary member configured to bear the developer and convey the developer to a developing position at which the electrostatic latent image formed on the image bearing member is developed, and
• a driving-force transmission member disposed on a side on which the developer container faces the image bearing member and on one end side of the developing rotary member in a rotation-axis direction of the developing rotary member, and configured to transmit driving force to the developing rotary member to rotate the developing rotary member;
• a driving device disposed on the side on which the developer container faces the image bearing member and on the one end side of the developing rotary member in the rotation-axis direction of the developing rotary member, and configured to provide the driving force to the driving-force transmission member;
• an airflow space portion disposed on the side on which the developer container faces the image bearing member, formed from the one end side to another end side of the developing rotary member in the rotation-axis direction of the developing rotary member, and configured to serve as a flow path of air that collects toner that scatters from the developing rotary member;
• a duct disposed on the one end side of the developing rotary member in the rotation-axis direction of the developing rotary member and 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, and connected to the airflow space portion such that air flows between the airflow space portion and the duct;
• and
• a drawing fan disposed on the side opposite to the side on which the developer container faces the image bearing member and on the one end side of the developing rotary member in the rotation-axis direction of the developing rotary member, and configured to draw air from an opening portion of the duct for generating airflow in the airflow space portion.
