Abstract
A droplet ejecting component of the present invention includes an ejecting component having a charge and discharge characteristic, an applying component being provided with a transistor, and an increasing component. The ejecting component ejects a droplet. When a control signal is inputted, the applying component applies an application voltage to the ejecting component, and the increasing component increases the impedance of the transistor.

A droplet ejecting apparatus comprising:
- an ejecting component which ejects a droplet, the ejecting component having a charge and discharge characteristic;
- an applying component which applies an application voltage to the ejecting component when a control signal is inputted, the applying component being provided with a transistor;
- and
- an increasing component which increases the impedance of the transistor,
- wherein the increasing component inputs to the applying component a control signal having an amplitude smaller than the amplitude of the application voltage.
A current control method in which passage of current through an ejecting component is controlled in a starting drive of a droplet ejecting apparatus including the ejecting component, an applying component, and an increasing component, wherein
- the ejecting component has a charge and discharge characteristic, and the ejecting component ejects a droplet,
- the applying component is provided with a transistor,
- the applying component applies an application voltage to the ejecting component when a control signal is inputted, and
