Abstract
An image forming method comprises steps of: ejecting charged matter applied an external force from a recording head placed opposed to a record medium; applying a voltage to an intermediate electrode installed between the recording head and the record medium and controlling flying of the ejected charged matter; applying a predetermined voltage to an auxiliary electrode placed between the intermediate electrode and the recording head, and controlling a potential gradient between the recording head and the intermediate electrode; and hitting the charged matter on the record medium.

An image forming method comprising steps of:
- ejecting charged matter from a recording head placed opposed to a record medium by applying an external force to the charged matter;
- applying a voltage to an intermediate electrode installed between the recording head and the record medium and control ling flying of the ejected charged matter;
- applying a predetermined voltage to an auxiliary electrode placed between the intermediate electrode and the recording head, and controlling a potential gradient between the recording head and the intermediate electrode;
- and hitting the charged matter on the record medium.
An image forming apparatus comprising:
- an ejection part electrode placed in the proximity of an ejection part of a recording head placed opposed to a record medium;
- an intermediate electrode placed between the recording head and the record medium;
- an auxiliary electrode placed between the recording head and the intermediate electrode;
- and voltage applying unit applying predetermined voltages to the ejection part electrode, the intermediate electrode, and the auxiliary electrode, wherein the charged matter ejected from the ejection part of the recording head placed opposed to the record medium flies by applying the external force to the charged matter and hits on the record medium, thereby forming an image on the recording medium.
An image forming apparatus comprising:
- an ejection part electrode placed in the proximity of an ejection part of a recording head placed opposed to a record medium;
- an intermediate electrode placed between the recording head and the record medium;
- an auxiliary electrode placed between the recording head and the intermediate electrode;
- and voltage applying unit applying predetermined voltages to the ejection part electrode, the intermediate electrode, and the auxiliary electrode, wherein the charged matter is stably ejected without disordering the ejecting direction such that said ejected charged matter from the ejection part of the recording head placed opposed to the record medium is controlled and flies by applying the external force to the charged matter and hits on the record medium, thereby forming an image on the recording medium.
