ABSTRACT:
A charging device includes: a charged body; a charging member that extends parallel to the surface of the charged body, a charging voltage being applied between the charging member and the charged body; a cleaning member that is in contact with the charging member, and that moves in an extending direction of the charging member to remove matters adhering to the charging member; and an air introduction path that introduces airflow flowing in one orientation with respect to the extending direction of the charging member at a position along the charging member, the cleaning member being in contact with the charging member in a case where the cleaning member moves in the one orientation, and the cleaning member being separated from the charging member in a case where the cleaning member moves in an orientation opposite to the airflow in a state in which the airflow is generated.
