ABSTRACT:
A charging device including a charging member configured to charge an image bearing member while the charging member is contacted with or is located so as to be close to the image bearing member when the charging device is set in an image forming apparatus; and a cleaning member configured to clean a surface of the charging member while contacting the surface of the charging member, wherein the pressure A at which the cleaning member is contacted with the charging member when the charging device is set in the image forming apparatus is greater than the pressure B at which the cleaning member is contacted with the charging member before the charging device is set in the image forming apparatus.
