Image forming apparatus

摘要

An image forming apparatus includes: an image bearer; a charging unit configured to charge a surface of the image bearer by causing a discharging member to discharge; a latent image forming unit configured to form a latent image on the surface of the image bearer charged by the charging unit; a developing unit configured to develop the latent image formed on the surface of the image bearer into a toner image with developer containing toner; an airflow generating unit configured to generate an airflow inside the image forming apparatus such that the airflow passes through at least the charging unit; an image-area-ratio information acquiring unit configured to acquire information on an image area ratio of the toner image; and a control unit configured to control the airflow generating unit so as to change a flow velocity of the airflow in accordance with the image area ratio.
