ABSTRACT:
A toner cartridge includes a container having a toner discharge opening formed therein, and an external member combined with the container so as to be relatively movable between a closed position at which the external member closes the toner discharge opening and an open position at which the external member uncovers the toner discharge opening. A compressible seal member extending along the peripheral edge of the toner discharge opening is disposed on the outer surface of the container. The seal member is compressed between the outer surface of the container and the inner surface of the external member. The seal member has a surface layer of cloth. A toner leakage preventing tape is stuck to a required site of the inner surface of the external member. The surface of the toner leakage preventing tape is non-adherent and has a coefficient of static friction .mu..sub.0, against the surface of a glazing, of 3.5 to 4.5, preferably 3.8 to 4.2.
