A cleaning member for removing a developer from a surface of a member to be cleaned includes a blade member configured to make contact with the member to be cleaned in a direction counter to a moving direction of the member to be cleaned, and a flexible plate-like supporting member configured to support the blade member, which includes one end with the blade member, the other end with a fixed portion fixed to a frame member, and a bent portion between the ends which is located outwardly away from the surface of the member to be cleaned relative to a segment connecting the fixed portion and a contact portion between the blade member and the member to be cleaned. The fixed portion arranged downstream of the moving direction of the member to be cleaned relative to the contact portion has a folded-back shape to nip part of the frame member.
