Abstract

A toner cartridge for use in an image forming device according to one example embodiment includes a housing having a reservoir for containing toner therein. The housing has an exit port in fluid communication with the reservoir. A cover is mounted on an exterior portion of the housing that is pivotable between a closed position blocking the exit port and an open position unblocking the exit port. The cover is biased toward the closed position. The cover has a projection extending therefrom such that a force on the projection causes the cover to move toward the open position.
