Patent attributes
Disclosed is an image forming apparatus that includes a recording head ejecting a liquid droplet; a liquid tank storing ink to be supplied to the recording head; a first flow path communicated with the recording head and the liquid tank; a liquid feeding unit provided in the first flow path; a second flow path provided parallel to the liquid feeding unit of the first flow path; and a fluid resistance control unit provided in the second flow path. The fluid resistance control unit changes fluid resistance in accordance with the flow rate of a flowing liquid and feeds, when the liquid droplet is ejected from the recording head, the liquid from the liquid tank to the recording head with the liquid feeding unit in a state in which the recording head and the liquid tank are communicated with each other via the second flow path.
