  • Patent number: 8849150
    Abstract: A charging device includes a charging member that includes a rotating shaft and charges a surface of a charging object while rotating in contact with the charging object, a cleaning member that includes a rotating shaft and removes unwanted matter from a surface of the charging member while rotating in contact with the charging member, and a bearing member that includes first and second receiving portions each having an open part on one side thereof and a substantially concave-shaped bottom on another side thereof. The first and second receiving portions receive circumferences of the rotating shafts of the charging member and the cleaning member, respectively, at the bottoms thereof. The open parts of the first receiving portion and the second receiving portion face respectively different directions. A part of an inner surface of the second receiving portion forms a part of an outer surface of the first receiving portion.
