Abstract
A recording apparatus wherein a recording medium is fed through the gap between recording electrodes and a rear electrode which are arranged to face each other. A magnetic toner is supplied to the gap between the recording medium and the recording electrodes. While under the state where a magnetic field is formed around the recording electrodes to retain toner particles on the recording electrodes, voltage pulses are selectively applied between the recording electrodes and the rear electrode to thereby transfer the toner particles on the recording electrodes to thereby the recording medium by means of coulomb forces for effecting a recording. The recording electrodes are constituted by recording electrode patterns mounted on a rigid board of an insulating non-magnetic material attached to the periphery of a cylindrical hollow member which houses a rotatable magnet roll.
