Abstract
An electrostatic recording apparatus includes a developing agent carrier member arranged along a predetermined developing agent convey path. A developing agent conveying section conveys a developing agent along a surface of the developing agent carrier member. A plurality of recording electrodes are arranged on the surface of the developing agent carrier member at a predetermined pitch. An opposite electrode is arranged to oppose the plurality of recording electrodes at a predetermined gap. A voltage applying section applies a voltage corresponding to recording information to each of the plurality of recording electrodes to selectively transfer the developing agent, which is conveyed along the surface of the developing agent carrier member, to the opposite electrode. The developing agent carrier member has a step at a portion on its surface shifted to an upstream side of a developing agent convey direction from a position closest to the opposite electrode. At least distal end portions of the plurality of recording electrodes project from this step toward the closest position to form projections. The projections are swingable in a direction of approaching or going away from the opposite electrode.
