When cleaning the corona wire, the cleaning tool main body is positioned on the charger main body or its holding member, and in this state, the cleaning tool main body is moved in the longitudinal direction of the corona wire. During this movement, the cleaning tool body moves not only in the longitudinal direction but also in a direction perpendicular to the longitudinal direction,
The movement will be in a zigzag pattern. In this case, since the resilient cleaning member is in pressure contact with the corona wire, the corona wire can be cleaned by moving the cleaning tool main body. Moreover, since the pressing force of the cleaning member against the corona wire is set so as not to become excessive, the corona wire will not be accidentally cut during cleaning. This cleaning is performed effectively because the cleaning member moves in a zigzag pattern.
