Abstract
An image recording apparatus comprises an aperture electrode for modulating and regulating a flow of charged toner particles, and a vibrating device for vibrating the aperture electrode. The vibration generated by the vibrating device is a progressive wave transmitted in the aperture electrode. Since all of the apertures of the aperture electrode efficiently vibrate at a sufficient amplitude, adhesion of the toner particles to the aperture electrode is easily prevented.
