Abstract
A corona charger conventionally includes a sheet-like shutter and a holding member configured to hold an end of the shutter, and the replacement of a charging electrode is difficult. To solve this problem, the holding member configured to hold the end of the shutter is set to be movable along the longitudinal direction of a shield to a winding member of the shutter more than a supporting member configured to replaceably support the charging electrode.
