Abstract
An electrostatic latent image is formed on an image carrier. A plurality of development cartridges include toner and are adapted to face the image carrier at a development position, respectively. The development cartridges cause the toner to adhere onto the image carrier to develop the electrostatic latent image as a toner image. A development device is configured to be rotatable around an rotational axis thereof. The development device houses the plurality of development cartridges around the rotational axis. A duct includes an inlet port through which air in the vicinity of the development position is sucked and an outlet port from which the sucked air is exhausted to the outside of the image forming apparatus. The duct covers an outer peripheral surface of the development device.
