PURPOSE: To converge an ion in a slit by a tilt insulation shield in an insulation housing and attain miniaturization of an electrification device, by arranging a pair of conductive plates to be opposed to a bottom part of the insulation housing of this device and a corona wire capable of radiating an ion in a surface of a photoconductor to be separated by a prescribed distance from this conductive plate. CONSTITUTION: In a self-cleaning electrification device 20 charged with a charge receiver surface, an insulation housing 21 surrounded substantially in upper, side and lower surfaces is arranged, in a lower surface of this housing 21, a pair of opposed conductive electrodes 40, 45 are arranged, a slit is formed by the electrodes 40, 45. In the inside of this housing 21, a coronode 25 emitting an ion onto a charge holding surface 50 through the slit is arranged in a position separated from the electrodes 40, 45. Tilt wedges 22, 23 are arranged corresponding to the electrodes 40, 45 in the housing 21, an additional ion generated by the coronode 25 is converged to a center of the slit, to improve efficiency of the charge device.
