摘要：
An opening of a developer container is sealed by a sealing member which is easy to tear in a predetermined direction. The sealing member is composed of a main portion having a tear strip portion, and a leader portion protruding from the main portion as an extension from the tear strip portion. The main portion seals the opening. The tear strip portion is torn off from the main portion by pulling the leader portion in the predetermined direction. The main portion is adhered to an adhesion area surrounding the opening. The adhesion area has a box-like area recessed in the predetermined direction, at a location facing a part of the main portion adjacent to the base portion of the tear strip portion.
