Abstract
An image forming unit includes a developing device, a guiding member, and a sealing member. The developing device develops an electrostatic latent image formed on an image carrier that rotates. The developing device has a first ventilation hole that serves as a flow path for an airflow that is generated by rotation of the image carrier. The guiding member guides a recording material to the image carrier. The guiding member has a second ventilation hole that forms the flow path for the airflow in cooperation with the first ventilation hole. The sealing member is disposed between the first ventilation hole and the second ventilation hole. The sealing member has a first end in contact with the developing device and a second end in contact with the guiding member.
