An image forming apparatus according to the invention includes, in an apparatus body, an image carrier on which an electrostatic latent image is formed; and a rotary-type development unit being rotatable about an axis thereof and having a plurality of developing devices, which are used for developing the latent images formed on the image carrier. The rotary-type development unit is formed with cavities at an outer periphery thereof for receiving gas. The rotary-type development unit is rotated for sequentially advancing the gas in the cavities whereby the gas in the apparatus body is discharged out of the apparatus body.
