The image forming apparatus comprises: an ejection head which ejects a droplet of liquid onto a recording medium; an electric field generating device which generates an electric field, the electric field generating device being arranged in a position facing an ejection face of the ejection head across the recording medium; and a control device which controls intensity of the electric field to attract mist of the liquid toward the electric field generating device, the mist of the liquid being produced when the droplet of the liquid is ejected by the ejection head.
