Abstract
An imaging device provided with a latent image carrying body rotatably disposed to carry a latent image, a developing unit that develops the latent image carried on the carrying body by using a developer containing toner at least, and a duct disposed downstream of the developing unit and having a wall with an upstream suction port and a downstream suction port formed. An air flow path is formed by a surface of the latent image carrying body and a surface of the duct wall, between the upstream suction port and the downstream suction port. A gap of the air flow path is wider at the downstream side than at the upstream side with respect to the rotational direction of the latent image carrying body.
