Abstract
A toner cartridge including a hollow body of cylindrical form made of nonmagnetic material to serve as a container formed at its outer peripheral surface with a toner feeding slot extending lengthwise thereof, a first lid member attached to one end of the hollow body and formed at the outer peripheral surface of its end portion with a flange, a second lid member attached to the other end of the hollow body and formed at its bottom with a toner supply port, a cap member closing the toner supply port, and a sealing member that can be peeled off closing the toner feeding slot formed at the outer peripheral surface of the hollow body. The second lid member is formed of thin sheet metal by bending same at its outer peripheral edge portion in a manner to provide a minuscule clearance between a bent portion and the thin sheet metal and the hollow body is inserted at the other end thereof in the bent portion and secured in place. The hollow body is formed at its outer peripheral surface with a groove and the first lid member is formed at its outer periphery with a projection, so that the projection can be brought into locking engagement in the groove when the first lid member is attached to the hollow body.
