| description | A contact charging roller (11) which is in contact with and electrically charges a photosensitive drum (16) is provided on a center shaft (11-1), and includes a roller-shaped conductive foam material portion (11-2) covering the shaft, and a tubular-shaped conductive resin material portion (11-3) covering the foam portion. The foam portion has an electric resistance of 9 x 10 OMEGA or less, the resin portion includes conductive agents and has a surface electric resistance in a range from 1 x 10 OMEGA / &squ& or more to 9 x 10 OMEGA / &squ& or less, and a hardness of the charging roller as a whole is Asker F 90 DEG or less. An image forming unit includes the charging member and the drum. An electrophotographic image forming apparatus supplies a recording paper to the unit, transfers an image from the drum to the paper, and discharges the image-transferred paper. |
