An image forming device includes a charging roller that charges a body-to-be-charged by press-contacting and is rotated by the rotating body-to-be-charged, a first receiving portion that supports a supporting portion provided at the charging roller, and causes the charging roller to press-contact the body-to-be-charged, a cleaning member that press-contacts a surface of the charging roller and cleans the charging roller, and a second receiving portion that supports a supporting portion provided at the cleaning member, and causes the cleaning member to press-contact the charging roller. At least one of the first and second receiving portions imparts a degree of freedom at a first receiving portion side to the supporting portion of the charging roller in a direction of press-contacting the body-to-be-charged, and imparts a degree of freedom at a second receiving portion side to the supporting portion of the cleaning member in a direction of press-contacting the charging roller.
