1. An image forming apparatus comprising:
a rotating photoreceptor;
an exposure portion configured to include a substrate having a plurality of light emitting portions arranged along a rotation axis direction of the photoreceptor and exposes the photoreceptor to form a latent image on the photoreceptor;
a development portion configured to develop a latent image formed on the photoreceptor with toner;
a first fan configured to generate an airflow for cooling the exposure portion;
an exposure duct configured to guide the airflow generated by the first fan along a longitudinal direction of the substrate;
a second fan configured to generate an airflow for cooling the development portion;
a development duct configured to guide the airflow generated by the second fan along the rotation axis direction of the development portion; and
a first duct communicating with the exposure duct and the development duct, the first duct configured to exhaust air introduced from the exposure duct and exhaust air introduced from the development duct.
