A blade member, including a rubber portion, is contacted to the rotatable member, with a metal plate portion supported to the blade member. A frame, formed of a resin material, supports the blade member. A seal member, extending in a direction crossing an axial direction of the rotatable member so as to contact the rotatable member, is provided on the frame to be contacted to a portion of the rubber portion and the metal plate portion of the blade member.
