An electrostatic actuator for forming an electric field for transporting the particles of a developer having a predetermined charge in a predetermined direction. A plurality of stripe-like drive electrodes are continuously formed on only one of opposite sides of a substrate in parallel. Pins are affixed to three electrode terminals and contact every third drive electrode selected in matching relation to the electrode terminals. The three terminals are held on an electrode connector which is fitted on one edge of the substrate. The portions of the pins contacting the drive electrodes are thinner than the portions connected to the electrode terminals.
