Claims

[Scope of Claim for Utility Model Registration] A document image is formed on a photoreceptor, the formed electrostatic latent image is developed, the developed image is transferred to transfer paper by a transfer charger, and the transfer paper is An image forming apparatus configured to be separated from a photoreceptor by a separation charger and then fixed therein includes a case for accommodating the image forming apparatus, and exhausting ozone generated by the separation charger and the transfer charger inside the case to the outside of the case. An exhaust fan whose air volume can be switched between large and small; an ozone filter having an exhaust path for exhausting ozone-containing air by the exhaust fan and disposed in a position to cross the exhaust path; and the ozone filter. In contrast, the exhaust fan is driven at a high speed with a large air volume during a predetermined period after the end of the image forming period, and at a medium speed with a small air volume outside of this high speed driving period. Features: Ozone removal device for image forming equipment.
