Claims

[Scope of utility model registration request]

A double-structure convex portion is formed around the toner discharge port formed in the replaceable toner cartridge, and the convex portion surrounds the discharge port and has a sealing seal attached thereto.
The shape of the convex portion of the double structure is formed such that the adhesion area gradually decreases at both longitudinal ends of the convex portion of the double structure, and further, among the convex portions of the double structure,
A replaceable toner cartridge characterized in that the adhesion area of the inner protrusion to the toner discharge port is larger than the adhesion area of the outer protrusion.
