Abstract
An apparatus for forming an image on a recording medium by deposition of a toner, including a particle-flow modulating electrode member having apertures formed therethrough and control electrodes corresponding to the apertures, a toner supply device including a toner carrier disposed on one of opposite sides of the electrode member, for carrying a layer of the toner to the apertures, and a voltage applying device for applying a controlled voltage to each control electrode, to thereby modulate flows of the toner particles through the apertures toward the recording medium located on the other side of the electrode member. The apparatus includes a device by which corresponding portions of the toner carrier and the particle-flow modulating electrode member which are adjacent to the apertures are biased against each other for contact therebetween.
