Abstract
In an image recording apparatus of this invention, a high voltage is applied to a blade for scratching a brush roller on which the toner particles are supported. The high voltage applicator is installed in an image recording apparatus which supplies toner particles in the vicinity of a particle control electrode so as to form a mist of toner particles by scratching a brush roller on which the toner particles are supported. The particle control electrode includes apertures allowing passage of toner particles to control image information. An image is formed on a recording medium provided at an opposite side of a toner particle supplying source. The tip of the blade to which a high voltage is applied generates a corona discharge, so that the toner particles can obtain a required amount of charge and the electric field enabling the toner particles to pass through the apertures can be controlled easily.
