Abstract
In an image recording apparatus in which toner carried on a toner carry roller is supplied to an aperture electrode in contact with the aperture electrode, the aperture electrode is elastically supported through an electrode supporter formed of elastomer such as rubber, and the toner carry roller is designed in a barrel shape. Therefore, the contact pressure between the aperture electrode and the toner carry roller is constant over all positions due to the expanding action of the electrode supporter and the toner is uniformly supplied to all the apertures of the aperture electrode. As a result, a uniform-density toner image can be formed over all the positions.
