ABSTRACT:
A toner jet recording apparatus having a particle-flow modulating electrode member having multiple apertures, a back electrode for supporting a recording medium interposed between the back electrode and the electrode member, and a control circuit for applying controlled electric signals to the electrode member and the back electrode, for causing flows of electrostatically charged toner particles through the selected apertures toward the back electrode. The apparatus is provided with an oscillating device for vibrating the electrode member, in a vibration mode in which an antinode is substantially aligned with a portion of the electrode member through which the apertures are formed. The oscillating device prevents plugging of the apertures with the particles.
