Abstract

An image forming apparatus of the present invention includes a casing, an image forming unit, and an air conditioning device. The image forming unit includes a case accommodating at least a photoconductive element therein and formed with an opening for image transfer via which the photoconductive element is partly exposed to the outside. The opening is the only opening that might allow substances harmful to image formation into the case when the image forming unit is mounted to the casing. The air conditioning device removes the harmful substances flowing into the image forming unit from the outside.
