Abstract
Adhesion of particles to a liquid ejecting head due to an electric field generated at an electric power supply wire disposed in the liquid ejecting head can be suppressed. The liquid ejecting head is provided with a conductive member covering at least a part of the electric power supply wire for supplying electric power to an ejection energy generating unit configured to generate ejection energy for ejecting liquid, with an insulator therebetween. The conductive member covers the electric power supply wire in a coverage determined based on a relative movement speed between an ejection port and a print medium, a size of particles floating between an ejection port forming surface and the print medium, an electric charge amount of the particles, and a voltage applied to the electric power supply wire.
