Abstract
A charging device includes a charging member in contact with or adjacent to a charged body, a charge housing that holds the charging member, bearing members that rotatably support the charging member, at least one of the bearing members being a conductive bearing member, pressing members that press the bearing members toward the charged body, at least the pressing member for the conductive bearing member being formed of a conductive material, a platelike power supply member in contact with the pressing member for the conductive bearing member, and positioning mechanisms that position the bearing members. The power supply member has a platelike extending portion. The positioning mechanism provided on a power supplied side of the charging member includes a positioning portion provided in the conductive bearing member, and a positioned portion provided in the extending portion. The positioned portion engages with the positioning portion when the extending portion elastically deforms.
