20100201775IMAGE FORMING APPARATUS - An image forming apparatus in one embodiment of the present invention is an image forming apparatus that includes a main body that performs processing to form an image on a recording paper, the image forming apparatus including, an ion generating section that is external to the main body, generates ions and emits those ions to the outside.08-12-2010
20100201776IMAGE FORMING APPARATUS - An ion generator for generating positive ions and negative ions is externally attached above a main body of an image forming apparatus. A ratio between positive ions and negative ions which are generated by the ion generator is switched between two ratios in accordance with whether the image forming apparatus is in an operating state or a standby state so that more negative ions are emitted during the operating state. This makes it possible to suppress an effect of an exhaust gas which contains chemical emissions such as an odor and a VOC and which is discharged from the image forming apparatus and to purify an indoor air.08-12-2010
