A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes a rotatable photosensitive drum; a charging roller for contacting and electrically charging the drum; a spacer for supporting a rotation shaft of the charging roller to space the drum from the charging roller; and an urging member for contacting the spacer to urge the charging roller toward the drum; wherein the spacer is movable between a first position for spacing the charging roller from the drum and a second position for contacting the charging roller to the drum, and an urging force of the urging member applied to the spacer is smaller when the spacer is in the second position than when the spacer is in the first position. |
