Abstract:
A charging apparatus includes a charging roller and a cleaning member. The charging roller charges a surface of an image bearing body. The cleaning member extends in a longitudinal direction parallel to the charging roller and that cleans the charging roller. The charging apparatus includes a bearing and a supporting member. The bearing supports a shaft of the charging roller. The cleaning member is mounted to the supporting member the cleaning member is held between the supporting member and the charging roller. The supporting member includes a surface to which the cleaning member is mounted, the surface being a curved surface configured to a circumferential surface of the charging roller. The supporting member includes a surface to which the cleaning member is mounted, the surface including a flat portion extending upstream with respect to rotation of the charging roller and a curved portion extending downstream.
