Abstract
A developing device includes a development roller that holds developer containing toner and carrier, rotates and transports the developer to a development area, and develops a latent image using the toner; a housing that has a first opening that opens towards the image holding member, and that holds the development roller; an airflow path that has a second opening that opens towards the image holding member at a location below the first opening; a blower that causes air in the airflow path to be sent in a direction in which the toner scattered between the housing and the image holding member is sucked from the second opening; and a magnetic plate opposing an end portion of the development roller in a direction of an axis of rotation of the development roller and extending so as to surround the development roller in a direction of rotation of the development roller.
