ABSTRACT:
A corona discharger is swingably and elastically supported in the direction contacting with or separating from a photosensitive drum always in the state urged toward the photosensitive drum side, and a supporting arm provided integrally with the corona discharger is contacted with the photosensitive drum, a shaft or relatively fixedly disposed member relative to the photosensitive drum, thereby positioning it relative to the photosensitive drum of the corona discharger. Therefore, an interval between the photosensitive drum and the corona discharger can always be maintained constant with a relatively simple structure, and can also perform always stable corona discharging operation.
