A hollow cylindrical cap is rotatably attached to a container body opening provided in one end of a hollow cylindrical container body. A seal member around the container body opening forms a seal between the container body and the cap. Once the cap is attached to the container body, pressing chips are circumferentially slidably engaged with a flange, and the seal member is pressure-sealed to a pressure-seal portion. A toner container identification is contiguous with the rear edge of one of the pressing chips. The toner container identification is formed by denting one part of the cap so its outer surface radially protrudes outward, and has a predetermined cross-section.
