Abstract
A charging device for charging a charged member includes a charging member for contacting the charged member to charge the charged member. A contact-separation device is provided for contacting/separating the charging member to/from the charged member. A power supply device supplies power to the charging member, in which a power supply path can be opened. The power supply device is constituted so that when the charging member contacts the charged member, the power supply path is closed, and when the charging member is separated from the charged member, the power supply path is opened.
