Patent ID: 7387367

Claim:
An image forming apparatus, comprising: 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; 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; and a movement device which adjusts distance between the electric field generating device and the ejection head, wherein: based on the occurrence the ejection head switching from a non-ejection state to an ejection state, the control device reduces voltage applied to the electric field generating device to reduce the intensity of the electric field generated by the electric field generating device, and controls the movement device to increase the distance between the electric field generating device and the ejection head; and based on the occurrence the ejection head switching from the ejection state to the non-ejection state, the control device increases the voltage applied to the electric field generating device to increase the intensity of the electric field generated by the electric field generating device, and controls the movement device to reduce the distance between the electric field generating device and the ejection head.
