PURPOSE:To provide an electrostatic recording apparatus which positively prevents the inconvenient fusion of a developing agent to a recording electrode, and forms a clear recording image of high resolving power and high image quality in a stable manner for a long time. CONSTITUTION:A surface layer 5b of a cylindrical electrode 5 is formed of an elastic material having the surface hardness 20 deg.-90 deg. (measured according to JIS spring method) and the volume resistivity 10<6>-10<16> [OMEGA.cm]]. On the other hand, a recording electrode EL is provided to project from a step G in a swaying fashion. The peripheral surface of the cylindrical electrode 5 and the upper surface of the recording electrode EL are arranged to be in tight contact with each other when a magnetic toner (d) is not supplied to a recording part W. Therefore, the magnetic toner (d) is never excessively pressed in contact between the electrodes. The upper surface of the recording electrode EL can be wiped by the peripheral surface of the cylindrical electrode 5 through the sliding contact therebetween. |
