Abstract
A device disposed in an exhaust section of image forming equipment for removing ozone generated in the equipment. An ozone filter and an agent container containing an ozone decomposing agent therein are constructed into a single unit. The agent contained in the body of the container is prevented from blocking small openings which allow the volatile matter of the agent to pass therethrough. A seal member and flanges surrounding the open end of the container body are adhered to each other by a layer of adhesive and a two-sided adhesive tape, whereby the open end is closed before the device is used.
