Charging device |
摘要 |
<p>A corona charging device (52) has a plurality of discharge electrodes (2c) to which a high voltage from a voltage generating section 63 is applied. The discharge electrodes (2c) are within an electrically conductive case (2a) and separated from a photoreceptor (51) by an electrically biased grid (2d). The discharge current through the discharge electrodes (2c) required for a uniform charging of the photoreceptor is minimized, thereby minimizing the amount of generated ozone. This is achieved by keeping the ratios of the grid current Ig, leakage current Ic and the current Id flowing through the photoreceptor (51) within specific ranges. <IMAGE></p> |
