Abstract
An ozone removing device suitable for use in an image forming apparatus using an electrophotographic process, such as a copier, a laser printer or a facsimile machine, includes a container for containing therein a quantity of a volatile ozone removing agent. Thus, the vaporized or volatilized ozone removing agent flows out of the container through its mount and diffuses into the surrounding atmosphere where it decomposes and removes the ozone when encountered. A filter formed with a plurality of through-holes is fixedly attached to the mouth of the container so that the rate of volatilization of the volatile ozone removing agent is properly controlled, to thereby provide a prolonged ozone removing action. Preferably, a seal is adhesively and sealingly attached to the filter to normally keep the through-holes closed. The seal is removed at least partly to set one or more of the through-holes open after placing the present ozone removing device in position.
